Subjects: subject: High Energy Physics - Theory (hep-th)

description: We consider the general hypermultiplet Low-Energy Effective Action (LEEA) that may appear in quantized, four-dimensional, N=2 supersymmetric, gauge theories, e.g. in the Coulomb and Higgs branches. Our main purpose is a description of the exact LEEA of n magnetically charged hypermultiplets. The hypermultiplet LEEA is given by the N=2 supersymmetric Non-Linear Sigma-Model (NLSM) with a 4n-dimensional hyper-K"ahler metric, subject to non-anomalous symmetries. Harmonic Superspace (HSS) and the NLSM isometries are very useful to constrain the hyper-K"ahler geometry of the LEEA. We use N=2 supersymmetric projections of HSS superfields to N=2 linear (tensor) O(2) and O(4) multiplets in N=2 Projective Superspace (PSS) to deduce the explicit form of the LEEA in some particular cases. As the by-product, a simple new classification of all multi-monopole moduli space metrics having su(2)_R symmetry is proposed in terms of real quartic polynomials of 2n variables, modulo Sp(n) transformations. The 4d hypermultiplet LEEA for n=2 can be encoded in terms of an elliptic curve.

description: We present a new hydrodynamic scheme named Godunov Density-Independent Smoothed Particle Hydrodynamics (GDISPH), that can accurately handle shock waves and contact discontinuities without any manually tuned parameters. This is in contrast to the standard formulation of smoothed particle hydrodynamics (SSPH), which requires the parameters for an artificial viscosity term to handle the shocks and struggles to accurately handle the contact discontinuities due to unphysical repulsive forces, resulting in surface tension that disrupts pressure equilibrium and suppresses fluid instabilities. While Godunov SPH (GSPH) can handle the shocks without the parameters by using solutions from a Riemann solver, it still cannot fully handle the contact discontinuities. Density-Independent Smoothed Particle Hydrodynamics (DISPH), one of several schemes proposed to handle contact discontinuities more effectively than SSPH, demonstrates superior performance in our tests involving strong shocks and contact discontinuities. However, DISPH still requires the artificial viscosity term. We integrate the Riemann solver into DISPH in several ways, yielding some patterns of GDISPH. The results of standard tests such as the one-dimensional Riemann problem, pressure equilibrium, Sedov-Taylor, and Kelvin-Helmholtz tests are favourable to GDISPH Case 1 and GDISPH Case 2, as well as DISPH. We conclude that GDISPH Case 1 has an advantage over GDISPH Case 2, effectively handling shocks and contact discontinuities without the need for specific parameters or introducing any additional numerical diffusion.

A UV Complete Framework of Freeze-in Massive Particle Dark Matter

description: We propose a way to generate tiny couplings of freeze-in massive particle dark matter with the Standard Model particles dynamically by considering an extension of the electroweak gauge symmetry. The dark matter is considered to be a singlet under this extended gauge symmetry which we have assumed to be the one in a very widely studied scenario called left-right symmetric model. Several heavy particles, that can be thermally inaccessible in the early Universe due to their masses being greater than the reheat temperature after inflation, can play the role of portals between dark matter and Standard Model particles through one loop couplings. Due to the loop suppression, one can generate the required non-thermal dark matter couplings without any need of highly fine tuned Yukawa couplings beyond that of electron Yukawa with the Standard Model like Higgs boson. We show that generic values of Yukawa couplings as large as $\mathcal{O}(0.01)$ to $\mathcal{O}(1)$ can keep the dark matter out of thermal equilibrium in the early Universe and produce the correct relic abundance later through the freeze-in mechanism. Though the radiative couplings of dark matter are tiny as required by the freeze-in scenario, the associated rich particle sector of the model can be probed at ongoing and near future experiments. The allowed values of dark matter mass can remain in a wide range from keV to TeV order keeping the possibilities of warm and cold dark matter equally possible.

Improved convergence of the spectral proper orthogonal decomposition through time shifting

description: Spectral proper orthogonal decomposition (SPOD) is an increasingly popular modal analysis method in the field of fluid dynamics due to its specific properties: a linear system forced with white noise should have SPOD modes identical to response modes from resolvent analysis. The SPOD, coupled with the Welch method for spectral estimation, may require long time-resolved data sets. In this work, a linearised Ginzburg-Landau model is considered in order to study the method's convergence. SPOD modes of the white-noise forced equation are computed and compared with corresponding response resolvent modes. The quantified error is shown to be related to the time length of Welch blocks (spectral window size) normalised by a convective time. Subsequently, an algorithm based on a temporal data shift is devised to further improve SPOD convergence and is applied to the Ginzburg-Landau system. Next, its efficacy is demonstrated in a numerical database of a boundary layer subject to bypass transition. The proposed approach achieves substantial improvement in mode convergence with smaller spectral window sizes with respect to the standard method. Furthermore, SPOD modes display growing wall-normal and span-wise velocity components along the stream-wise direction, a feature which had not yet been observed and is also predicted by a global resolvent calculation. The shifting algorithm for the SPOD opens the possibility for using the method on datasets with time series of moderate duration, often produced by large simulations.

description: Predicting future frames of a video is challenging because it is difficult to learn the uncertainty of the underlying factors influencing their contents. In this paper, we propose a novel video prediction model, which has infinite-dimensional latent variables over the spatio-temporal domain. Specifically, we first decompose the video motion and content information, then take a neural stochastic differential equation to predict the temporal motion information, and finally, an image diffusion model autoregressively generates the video frame by conditioning on the predicted motion feature and the previous frame. The better expressiveness and stronger stochasticity learning capability of our model lead to state-of-the-art video prediction performances. As well, our model is able to achieve temporal continuous prediction, i.e., predicting in an unsupervised way the future video frames with an arbitrarily high frame rate.

description: The expansion of Web of Science Core Collection (WoSCC) over the recent years has partially accounted for the "norm" of growth of research output in many bibliometric analysis studies. However, the expansion patterns of different citation indexes may be different, which may benefit some disciplines but hinder others. Utilizing Science Citation Index Expanded (SCIE), Social Sciences Citation Index (SSCI), and Arts & Humanities Citation Index (A&HCI), this study attempts to elaborate on WoSCC's coverage expansion patterns among these three databases from 2001 to 2020. Results show that different from SCIE/SSCI, both the annual publication volumes in the A&HCI database and all A&HCI journals have remained relatively stagnant in all document types considered scenario or have gained relatively slight increases in only citable items considered scenario. Although the number of A&HCI journals also has increased remarkably, the average journal publication volume of A&HCI journals has decreased gradually if all document types are considered or kept relatively stagnant when citable items only are considered. Besides, the A&HCI database has ceased the systematic index of individually selected items from SCIE/SSCI journals since 2018. The study finally discusses the possible causes and consequences of the unbalanced expansion of WoSCC's different citation indexes.

description: In this paper, we study the numerical approximation of a coupled system of elliptic-parabolic equations posed on two separated spatial scales. The model equations describe the interplay between macroscopic and microscopic pressures in an unsaturated heterogeneous medium with distributed microstructures as they often arise in modeling reactive flow in cementitious-based materials. Besides ensuring the well-posedness of our two-scale model, we design two-scale convergent numerical approximations and prove a priori error estimates for the semidiscrete case. We complement our analysis with simulation results illustrating the expected behaviour of the system.

description: The cross-correlation study of the unresolved $γ$-ray background (UGRB) with galaxy clusters has a potential to reveal the nature of the UGRB. In this paper, we perform a cross-correlation analysis between $γ$-ray data by the Fermi Large Area Telescope (Fermi-LAT) and a galaxy cluster catalogue from the Subaru Hyper Suprime-Cam (HSC) survey. The Subaru HSC cluster catalogue provides a wide and homogeneous large-scale structure distribution out to the high redshift at $z=1.1$, which has not been accessible in previous cross-correlation studies. We conduct the cross-correlation analysis not only for clusters in the all redshift range ($0.1 < z < 1.1$) of the survey, but also for subsamples of clusters divided into redshift bins, the low redshift bin ($0.1 < z < 0.6$) and the high redshift bin ($0.6 < z < 1.1$), to utilize the wide redshift coverage of the cluster catalogue. We find the evidence of the cross-correlation signals with the significance of 2.0-2.3$σ$ for all redshift and low-redshift cluster samples. On the other hand, for high-redshift clusters, we find the signal with weaker significance level (1.6-1.9$σ$). We also compare the observed cross-correlation functions with predictions of a theoretical model in which the UGRB originates from $γ$-ray emitters such as blazars, star-forming galaxies and radio galaxies. We find that the detected signal is consistent with the model prediction.

Experimental investigation of wake development and mixing behind a multi-scale array of bars
Creators: name: Baj, Paweł
Publisher: name: Imperial College London
Year: 2018

description: This thesis considers the experimental investigation of the near wakes of arrays composed of bars of uniform and non-uniform thickness (i.e. single and multi-scale arrays). The velocity and passive scalar concentration fields are measured by means of Particle Image Velocimetry (PIV) and Planar Laser Induced Fluorescence (PLIF). The objective is to identify distinctive features associated with the multi-scale turbulence forcing and to characterise their importance for the flow's dynamics and the scalar dispersion. The velocity fields' inspection reveals shedding modes associated with the particular bars. Additional energetic coherent fluctuations are spotted in the vicinities of wakes’ intersections in the multi-scale array case. In order to better understand these features, an energy budget of the multi-scale flow is considered in its triple-decomposed version where coherent and stochastic fluctuations are treated separately. The latter reveals, amongst other things, that the additional coherence is produced by triadic interactions of the primary shedding fluctuations. The analysis of scalar dispersion shows a specific way of fluid exchange between adjacent wakes, i.e. a quasi-periodic bursting. This phenomenon also appears to be triggered as the wakes’ intersection occurs. Its effects on the quantitative scalar dispersion statistics are carefully studied for the multi-scale array case and related to the underlying velocity field. A considerable part of this thesis is dedicated to the development of tools needed in the course of the data analysis. Two major outcomes are the PLIF quantification technique and the triple decomposition technique. The former is a major improvement to classical quantification approaches, accounting for a non-linear fluorescent response of the dye, strong attenuation effects and so-called secondary fluorescence. The developed triple decomposition methodology allows distinguishing a number of separate coherent fluctuations coexisting in a flow, e.g. shedding modes of particular bars (as opposed to a singular mode usually considered in the literature).

description: In the context of avatar-mediated communication, it is crucial for the face-to-face interlocutor to sense the operator's presence and emotions via the avatar. Although androids resembling humans have been developed to convey presence through appearance and movement, few studies have prioritized deepening the communication experience for both operator and interlocutor using android robot as an avatar. Addressing this gap, we introduce the ``Cybernetic Avatar `Yui','' featuring a human-like head unit with 28 degrees of freedom, capable of expressing gaze, facial emotions, and speech-related mouth movements. Through an eye-tracking unit in a Head-Mounted Display (HMD) and degrees of freedom on both eyes of Yui, operators can control the avatar's gaze naturally. Additionally, microphones embedded in Yui's ears allow operators to hear surrounding sounds in three dimensions, enabling them to discern the direction of calls based solely on auditory information. An HMD's face-tracking unit synchronizes the avatar's facial movements with those of the operator. This immersive interface, coupled with Yui's human-like appearance, enables real-time emotion transmission and communication, enhancing the sense of presence for both parties. Our experiments demonstrate Yui's facial expression capabilities, and validate the system's efficacy through teleoperation trials, suggesting potential advancements in avatar technology.

description: We investigate how superradiance affects the generation of baryon asymmetry in a universe with rotating primordial black holes, considering a scenario where a scalar boson is coupled to the heavy right-handed neutrinos. We identify the regions of the parameter space where the scalar production is enhanced due to superradiance. This enhancement, coupled with the subsequent decay of the scalar into right handed neutrinos, results in the non-thermal creation of lepton asymmetry. We show that successful leptogenesis is achieved for masses of primordial black holes in the range of order $O(0.1~{\rm g}) - O(10~{\rm g})$ and the lightest of the heavy neutrino masses, $M_N \sim O(10^{12})~{\rm GeV}$. Consequently, regions of the parameter space, which in the case of Schwarzchild PBHs were incompatible with viable leptogenesis, can produce the observed matter-antimatter asymmetry.

description: Nonadiabatic holonomic quantum computation (NHQC) has been developed to shorten the construction times of geometric quantum gates. However, previous NHQC gates require the driving Hamiltonian to satisfy a set of rather restrictive conditions, reducing the robustness of the resulting geometric gates against control errors. Here we show that nonadiabatic geometric gates can be constructed in an extensible way, called NHQCþ, for maintaining both flexibility and robustness against certain types of noises. Consequently, this approach makes it possible to incorporate most of the existing optimal control methods, such as dynamical decoupling, composite pulses, and a shortcut to adiabaticity, into the construction of single-looped geometric gates. Furthermore, this extensible approach of geometric quantum computation can be applied to various physical platforms such as superconducting qubits and nitrogen-vacancy centers. Specifically, we performed numerical simulation to show how the noise robustness in recent experimental implementations [Phys. Rev. Lett. 119, 140503 (2017); Nat. Photonics 11, 309 (2017)] can be significantly improved by our NHQCþ.approach. These results cover a large class of new techniques combing the noise robustness of both geometric phase and optimal control theory.

description: In this paper, we build on the work of [T. Hughes, G. Sangalli, VARIATIONAL MULTISCALE ANALYSIS: THE FINE-SCALE GREENS' FUNCTION, PROJECTION, OPTIMIZATION, LOCALIZATION, AND STABILIZED METHODS, SIAM Journal of Numerical Analysis, 45(2), 2007] dealing with the explicit computation of the Fine-Scale Green's function. The original approach chooses a set of functionals associated with a projector to compute the Fine-Scale Green's function. The construction of these functionals, however, does not generalise to arbitrary projections, higher dimensions, or Spectral Element methods. We propose to generalise the construction of the required functionals by using dual functions. These dual functions can be directly derived from the chosen projector and are explicitly computable. We show how to find the dual functions for both the $L^2$ and the $H^1_0$ projections. We then go on to demonstrate that the Fine-Scale Green's functions constructed with the dual basis functions consistently reproduce the unresolved scales removed by the projector. The methodology is tested using one-dimensional Poisson and advection-diffusion problems, as well as a two-dimensional Poisson problem. We present the computed components of the Fine-Scale Green's function, and the Fine-Scale Green's function itself. These results show that the method works for arbitrary projections, in arbitrary dimensions. Moreover, the methodology can be applied to any Finite/Spectral Element or Isogeometric framework.

Coherent dynamics of trapped ions within and outside the Lamb-Dicke regime
Creators: name: Joshi, Manoj
Publisher: name: Imperial College London
Year: 2018

description: From subatomic particles to macromolecules, quantum mechanics has a deep impact in understanding the interactions and nature of such constituents of matter. The paradoxical observations of entanglement in quantum systems is used in quantum computations. Ion traps are among the leading platforms which provide clean and highly controllable quantum systems. This thesis presents the study of quantum coherence aiming to devise and test coherent control with trapped ions in a Penning trap. Our apparatus contains one or more calcium ions that are confined in space using DC electric and magnetic fields. Doppler cooling and resolved sideband cooling of trapped ions are carried out to perform high fidelity quantum control. The ions are prepared in their motional ground state via a multi-stage resolved sideband cooling technique. The cooling methods are first verified through simulations. The axial mean phonon numbers for a single ion are measured to be 0.03 ± 0.01 and 0.012 ± 0.009 at 187 kHz and 420 kHz axial frequencies, respectively. The heating rate is measured to be 2.5 ± 0.5 phonons/s, which is consistent with the previous measurements in our system. Similarly, the radial motional modes of a single ion are cooled to 〈n_+ 〉<0.4 and 〈n_- 〉<0.6 from mean phonon numbers corresponding to each mode of around 100. Preliminary studies are carried out of the axial motional modes of a 1D chain and 2D planar crystals, extending sideband cooling to small ICC's in a Penning trap. Coherent control is examined in our system and the optical coherence time and motional coherence time are estimated to be approximately 1 ms and 0.5 s, respectively. Furthermore, a single ion is prepared outside the Lamb-Dicke regime via a sideband heating technique and coherent studies are performed in such a regime via a laser beam.

description: Web users can not be guaranteed that the results provided by Web search engines or recommender systems are either exhaustive or relevant to their search needs. Businesses have the commercial interest to rank higher on results or recommendations to attract more customers while Web search engines and recommender systems make their profit based on their advertisements. This research analyses the result rank relevance provided by the different Web search engines, metasearch engines, academic databases and recommender systems. We propose an Intelligent Search Assistant (ISA) that addresses these issues from the perspective of end-users acting as an interface between users and the different search engines; it emulates a Web Search Recommender System for general topic queries where the user explores the results provided. Our ISA sends the original query, retrieves the provided options from the Web and reorders the results. The proposed mathematical model of our ISA divides a user query into a multidimensional term vector. Our ISA is based on the Random Neural Network with Deep Learning Clusters. The potential value of each neuron or cluster is calculated by applying our innovative cost function to each snippet and weighting its dimension terms with different relevance parameters. Our ISA adapts to the perceived user interest learning user relevance on an iterative process where the user evaluates directly the listed results. Gradient Descent and Reinforcement Learning are used independently to update the Random Neural Network weights and we evaluate their performance based on the learning speed and result relevance. Finally, we present a new relevance metric which combines relevance and rank. We use this metric to validate and assess the learning performance of our proposed algorithm against other search engines. In some situations, our ISA and its iterative learning outperforms other search engines and recommender systems.

Parsing Turkish with the Lexical Functional Grammar Formalism
Creators: name: Gungordu, Zelal
name: Oflazer, Kemal
Publisher: name: arXiv
Year: 1994
Subjects: subject: Computation and Language (cs.CL)
subject: FOS: Computer and information sciences

description: This paper describes our work on parsing Turkish using the lexical-functional grammar formalism. This work represents the first significant effort for parsing Turkish. Our implementation is based on Tomita's parser developed at Carnegie-Mellon University Center for Machine Translation. The grammar covers a substantial subset of Turkish including simple and complex sentences, and deals with a reasonable amount of word order freeness. The complex agglutinative morphology of Turkish lexical structures is handled using a separate two-level morphological analyzer. After a discussion of key relevant issues regarding Turkish grammar, we discuss aspects of our system and present results from our implementation. Our initial results suggest that our system can parse about 82\% of the sentences directly and almost all the remaining with very minor pre-editing.

Comparing randomized benchmarking figure with average infidelity of quantum gate-set

description: Randomized benchmarking (RB) is a popular procedure used to gauge the performance of a set of gates useful for quantum information processing (QIP). Recently, Proctor et al. [Phys. Rev. Lett. 119, 130502 (2017)] demonstrated a practically relevant example where the RB measurements give a number $r$ very different from the actual average gate-set infidelity $ε$, despite past theoretical assurances that the two should be equal. Here, we derive formulas for $ε$, and for $r$ from the RB protocol, in a manner permitting easy comparison of the two. We show in general that, indeed, $r\neq ε$, i.e., RB does not measure average infidelity, and, in fact, neither one bounds the other. We give several examples, all plausible in real experiments, to illustrate the differences in $ε$ and $r$. Many recent papers on experimental implementations of QIP have claimed the ability to perform high-fidelity gates because they demonstrated small $r$ values using RB. Our analysis shows that such a statement from RB alone has to be interpreted with caution.

Baryogenesis in $R^2$-Higgs Inflation: the Gravitational Connection

description: $R^2$-Higgs inflation stands out as one of the best-fit models of Planck data. Using a covariant formalism for the inflationary dynamics and the production of helical gauge fields, we show that the observed baryon asymmetry of the Universe (BAU) can be obtained when this model is supplemented by a dimension-six CP-violating term $\sim (R/Λ^2)\, B_{μν} \widetilde{B}^{μν}$ in the hypercharge sector. At linear order, values of $Λ\simeq 2.5\times10^{-5}\ M_{\rm P}$ produce, in the $R^2$-like regime, sufficient helical hypermagnetic fields to create the observed matter-antimatter asymmetry during the electroweak crossover. However, the Schwinger effect of fermion pair production can play a critical role in this context, and that scale is significantly lowered when the backreaction of the fermion fields on the gauge field production is included. In all cases, the helical field configurations can remain robust against washout after the end of inflation.

Cometary ionosphere analysis from Rosetta multi-instrument dataset

Publisher: name: Imperial College London

description: The Rosetta spacecraft is the first spacecraft to ever escort a comet. It provided us with a unique opportunity to study comet Churyumov-Gerasimenko/67P from a close perspective and over a two-year time period. Comets are essentially composed of ice and dust. This ice sublimates and creates an envelop of gas around the nucleus, the so-called coma. This expanding gas is partially ionized through photo-ionization and electron-impact ionization, forming a cometary ionosphere, which is the object of my research. The on-board Rosetta instruments were able to continuously monitor the ambient environment, from the rendez-vous in August 2014, to the crash-landing of the spacecraft in 2016. They surveyed the comet during its low outgassing periods at large heliocentric distances, as well as during its peak of activity, for near-perihelion conditions (1.3 au) in summer 2015. The Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) instrument set provided in-situ measurements of the neutral and ion composition, as well as the total neutral densities. The Rosetta Plasma Consortium (RPC) sensors returned in-situ measurements of the surrounding plasma, from which were derived physical parameters such as: plasma densities, ionizing electron fluxes, spacecraft potential and electron temperatures. I was able to disentangle the physical processes responsible for the formation of the cometary plasma throughout the two-year escort phase and I evaluated their respective magnitudes. Electron-impact ionization, estimated from the RPC-Ion and Electron Sensor (IES) measurements, is a significant source of ionization at large heliocentric distance (>2 au). Photo-ionization by solar Extreme UltraViolet (EUV) radiation is the main ion source near perihelion. For large heliocentric distance (>2 au) conditions during the escort phase, I have applied a multi-instrument data-based ionospheric model to compute the plasma densities at Rosetta. In-situ measurements from the ROSINA instruments and the RPC-IES, together with the RPC-LAngmuir Probes were used to compute the instantaneous total ion number density. Very good agreements between the modelled plasma density and that measured by RPC--Mutual Impedance Probe (MIP) and RPC--LAP attested of the correct identification of the plasma production and loss processes included in the model. Near perihelion, the comet reached high outgassing rates and the medium was highly collisional at close cometocentric distances (<100km). Ion-neutral reactions and ion-electron dissociative recombinations are able to strongly affect the ion composition and densities. The ion chemical diversity and density profiles under these conditions were assessed using a numerical ionospheric model, which was also used to interpret the ion composition observed by ROSINA under different outgassing rates. These new findings have been contrasted with the ion composition observed at the very active comet Halley/1P, during the Giotto fly-by.

description: Fuzzy-Systeme sind im Allgemeinen statische Systeme. Des Weiteren lassen sich aber auch dynamische Systeme direkt durch Fuzzy-Funktionen und Regeln beschreiben. Ihre Dynamik ist dabei inhärent und wird nicht durch das Gewichten von dynamischen Modellen wie im Falle von Takagi–Sugeno–Kang-Systemen erreicht, sondern durch direkte Rückführung der Ausgangsgrößen eines Fuzzy-Systems. In diesem Beitrag werden vier verschiedene, zentrale Ansätze für Fuzzy-Systeme mit inhärenter Dynamik behandelt: rekurrente Fuzzy-Systeme, dynamische Fuzzy-Systeme, iterierte Fuzzy-Mengen und Fuzzy-Automaten.
Testing Stability of M-Theory on an S^1/Z_2 Orbifold

description: We analyse perturbatively, whether a flat background with vanishing G-flux in Horava-Witten supergravity represents a vacuum state, which is stable with respect to interactions between the ten-dimensional boundaries, mediated through the D=11 supergravity bulk fields. For this, we consider fluctuations in the graviton, gravitino and 3-form around the flat background, which couple to the boundary $E_8$ gauge-supermultiplet. They give rise to exchange amplitudes or forces between both boundary fixed-planes. In leading order of the D=11 gravitational coupling constant $κ$, we find an expected trivial vanishing of all three amplitudes and thereby stability of the flat vacuum in the static limit, in which the centre-of-mass energy $\sqrt{s}$ of the gauge-multiplet fields is zero. For $\sqrt{s}>0$, however, which could be regarded a vacuum state with excitations on the boundary, the amplitudes neither vanish nor cancel each other, thus leading to an attractive force between the fixed-planes in the flat vacuum. A ground state showing stability with regard to boundary excitations, is therefore expected to exhibit a non-trivial metric. Ten-dimensional Lorentz-invariance requires a warped geometry. Finally, we extrapolate the amplitudes to the case of coinciding boundaries and compare them to the ones resulting from the weakly coupled $E_8 \times E_8$ heterotic string theory at low energies.

Application of FPGAs to triggering in high energy physics
Creators: name: Summers, Sioni
Publisher: name: Imperial College London
Year: 2018

description: The High Luminosity upgrade of the LHC will increase the instantaneous luminosity to 5 × 10 34 cm −2 s −1 , resulting in an increase in the number of simultaneous proton-proton collisions per event (pileup) to the range 140-200. The CMS Level 1 Trigger system will be upgraded, and will reduce the 40 MHz event rate to 750 kHz. The system will perform a fast event reconstruction on FPGA devices, and select events for read out within a latency of 12.5 μs. The high level FPGA programming tool MaxCompiler is investigated for use in Level 1 Trigger applications. An existing trigger algorithm, originally developed with a Hardware Description Language, is reimplemented using MaxCompiler and compared to the original. Bitwise agreement between the outputs is observed, with half as many lines of code, at the expense of some extra FPGA resources. A hardware demonstration of a proposed Level 1 track reconstruction is presented, with a Kalman Filter track fit developed with MaxCompiler. The performance of the tracking is investigated, as well as the potential for developing advanced algorithms with low latency using the tool. A high tracking efficiency, and precise parameter resolutions, are achieved with a 3.7 μs latency in high pileup events. A boosted decision tree classifier, implemented with inference latency of a few clock cycles, is presented as a means to reject fake tracks. After the Level 1 Trigger, events are further processed on commodity PCs in the High Level Trigger (HLT). The High Luminosity LHC will also challenge the HLT, which is projected to require twenty times the processing power used during LHC Run II. Part of the HLT tracking is ported to Maxeler Dataflow Engines (DFEs), a hardware acceleration technology. A faster rate of processing is achieved, but with an initial latency of the host-DFE communication that limits the performance. Steps which might yield acceleration are identified.
