Seesaw mechanism in the sneutrino sector and its consequences

description: The seesaw-extended MSSM provides a framework in which the observed light neutrino masses and mixing angles can be generated in the context of a natural theory for the TeV-scale. Sneutrino-mixing phenomena provide valuable tools for connecting the physics of neutrinos and supersymmetry. We examine the theoretical structure of the seesaw-extended MSSM, retaining the full complexity of three generations of neutrinos and sneutrinos. In this general framework, new flavor-changing and CP-violating sneutrino processes are allowed, and are parameterized in terms of two $3\times 3$ matrices that respectively preserve and violate lepton number. The elements of these matrices can be bounded by analyzing the rate for rare flavor-changing decays of charged leptons and the one-loop contribution to neutrino masses. In the former case, new contributions arise in the seesaw extended model which are not present in the ordinary MSSM. In the latter case, sneutrino--antisneutrino mixing generates the leading correction at one-loop to neutrino masses, and could provide the origin of the observed texture of the light neutrino mass matrix. Finally, we derive general formulae for sneutrino--antisneutrino oscillations and sneutrino flavor-oscillations. Unfortunately, neither oscillation phenomena is likely to be observable at future colliders.

description: A SST survey in the NOAO Deep-Wide Field in Boötes provides a complete, 8-micron-selected sample of galaxies to a limiting (Vega) magnitude of 13.5. In the 6.88 deg$^2$ field sampled, 79% of the 4867 galaxies have spectroscopic redshifts, allowing an accurate determination of the local (z<0.3) galaxy luminosity function. Stellar and dust emission can be separated on the basis of observed galaxy colors. Dust emission (mostly PAH) accounts for 80% of the 8 micron luminosity, stellar photospheres account for 19%, and AGN emission accounts for roughly 1 %. A sub-sample of the 8 micron-selected galaxies have blue, early-type colors, but even most of these have significant PAH emission. The luminosity functions for the total 8 micron luminosity and for the dust emission alone are both well fit by Schechter functions. For the 8 micron luminosity function, the characteristic luminosity is νL_ν^*(8.0 \micron) = 1.8 \times 10^{10}$ \Lsun while for the dust emission alone it is 1.6 x 10^{10}$ \Lsun\null. The average 8 \micron luminosity density at z<0.3 is 3.1 x 10^7 \Lsun Mpc^{-3}, and the average luminosity density from dust alone is 2.5 x 10^7 \Lsun Mpc^{-3}. This luminos ity arises predominantly from galaxies with 8 \micron luminosities ($νL_ν$) between $2\times 10^9$ and $2 x 10^{10}$ \Lsun, i.e., normal galaxies, not LIRGs or ULIRGs.

Direct reference and belief attributions
Creators: name: Bryans, Joan Douglas
Publisher: name: University of British Columbia
Year: 2011

description: The aim of this dissertation is to provide a non-Fregean account of the functioning of belief attributions (BA's), specifically those of the form 'B believes that Fa' where 'a' is a proper name, which provides a satisfactory account of the phenomena associated with the substitution of co-referential names and with the use of vacuous names. After an intitial study of non-Fregean theories of reference, specifically those of Kripke, Kaplan and Donnellan in which Kaplan's introduction of content, of the singular proposition, is found to be necessary, an examination of certain proposed solutions for BA's, compatable with direct reference, is carried out. These proposals, namely those of Quine, Perry and Nathan Salmon, are all found wanting, the latter two due to their being, ultimately, Fregean. A non-Fregean approach is initiated beginning with an examination of our actual practices in using BA's. It is found that very different information can be conveyed by the use of the same sentence in the same context. While this differing information cannot be captured by means of the proposition expressed, it can be captured by treating the BA as an answer to a question. Belnap's logic of questions and answers is then developed to encompass vacuous terms and, with this in place, two distinct uses of BA's emerge. In one, the BA is used to provide a direct answer to the question; in the other it is used in order to modify the claim to truth of the embedded proposition, to provide a tentative answer. Problematic cases of BA's are then examined. It is found that substitution in all cases is permissible. Supposed difficulties with this position in the area of belief itself and with the explanation of action are discussed and resolved, the latter partly by means of the development and application of an account of 'why' questions and answers. The use of vacuous names is then investigated and a difference noted between cases in which the BA is used to provide a tentative answer and those in which it constitutes a direct answer. In the former case, the use of a vacuous name results in no answer being given. However, given the nature of tentative answers, no problems specific to belief attributions are generated in such cases. In order to deal with cases where the vacuous name occurs in a BA asserted as a direct answer, Evans' account of pretend games is invoked, though modified to permit a possible world account of counterfactuals.

description: A higher dimensional generalization of the cross product is associated with an adequate matrix multiplication. This index-free view allows for a better understanding of the underlying algebraic structures, among which are generalizations of Grassmann's, Jacobi's and Room's identities. Moreover, such a view provides a higher dimensional analogue of the decomposition of the vector Laplacian which itself gives an explicit index-free Helmholtz decomposition in arbitrary dimensions $n\ge2$.

description: We report on the fabrication and transport studies of a single-layer graphene p-n junction. Carrier type and density in two adjacent regions are individually controlled by electrostatic gating using a local top gate and a global back gate. A functionalized Al203 oxide that adheres to graphene and does not significantly affect its electronic properties is described. Measurements in the quantum Hall regime reveal new plateaus of two-terminal conductance across the junction at 1 and 3/2 times the quantum of conductance, e2/h, consistent with theory.

description: When a randomness is introduced at the level of real matrix elements, depending on its particular realization, a pair of eigenvalues can appear as real or form a complex conjugate pair. We show that in the limit of large matrix size the density of such real eigenvalues is proportional to the square root of the asymptotic density of complex eigenvalues continuated to the real line. This relation allows one to calculate the real densities up to a normalization constant, which is then applied to various examples, including heavy-tailed ensembles and adjacency matrices of sparse random regular graphs.

description: We measure star formation rates of ~50,000 optically-selected galaxies in the local universe (z~0.1), spanning a range from gas-rich dwarfs to massive ellipticals. We obtain dust-corrected SFRs by fitting the GALEX (UV) and SDSS (optical) photometry to a library of population synthesis models that include dust attenuation. For star-forming galaxies, our UV-based SFRs compare remarkably well with those derived from SDSS H alpha. Deviations from perfect agreement between these two methods are due to differences in the dust attenuation estimates. In contrast to H alpha, UV provides reliable SFRs for galaxies with weak or no H alpha emission, and where H alpha is contaminated with an emission from an AGN. We use full-SED SFRs to calibrate a simple prescription that uses GALEX UV magnitudes to produce good SFRs for normal star-forming galaxies. The specific SFR is considered as a function of stellar mass for (1) star-forming galaxies with no AGN, (2) those hosting an AGN, and for (3) galaxies without H alpha emission. We find that the three have distinct star formation histories, with AGN lying intermediate between the star-forming and the quiescent galaxies. Normal star forming galaxies (without an AGN) lie on a relatively narrow linear sequence. Remarkably, galaxies hosting a strong AGN appear to represent the massive continuation of this sequence. Weak AGN, while also massive, have lower SFR, sometimes extending to the realm of quiescent galaxies. We propose an evolutionary sequence for massive galaxies that smoothly connects normal star-forming galaxies to quiescent (red sequence) galaxies via strong and weak AGN. We confirm that some galaxies with no H alpha emission show signs of SF in the UV. We derive a UV-based cosmic SFR density at z=0.1 with smaller total error than previous measurements (abridged).

description: We study the dynamical Chern-Simons gravity as an effective quantum field theory, and discuss a broad range of its parameter space where the theory is valid. Within that validity range, we show that slowly rotating black holes acquire novel geometric structures due to the gravitational dynamical Chern-Simons term. In particular, the rotating black hole solutions get endowed with two, cap-like domains, emanating from the north and south poles in the standard Boyer-Lindquist coordinates. The domains extend out to a distance that is approximately a few percent of the black hole's size. The cap-like domains have an unusual equation of state, pointing to non-standard dynamics within the caps. In particular, the focusing condition for geodesics is violated in those domains. This in turn implies that the Hawking-Penrose singularity theorem cannot be straightforwardly applied to hypothetical probe matter placed within the Chern-Simons caps.

description: Mobility edges, separating localized from extended states, are known to arise in the single-particle energy spectrum of disordered systems in dimension strictly higher than two and certain quasiperiodic models in one dimension. Here we unveil a different class of mobility edges, dubbed anomalous mobility edges, that separate bands of localized states from bands of critical states in diagonal and off-diagonal quasiperiodic models. We first introduce an exactly solvable quasi-periodic diagonal model and analytically demonstrate the existence of anomalous mobility edges. Moreover, numerical multifractal analysis of the corresponding wave functions confirms the emergence of a finite band of critical states. We then extend the sudy to a quasiperiodic off-diagonal Su-Schrieffer-Heeger model and show numerical evidence of anomalous mobility edges. We finally discuss possible experimental realizations of quasi-periodic models hosting anomalous mobility edges. These results shed new light on the localization and critical properties of low-dimensional systems with aperiodic order.
Real analytic solutions for marginal deformations in open superstring field theory

description: We construct analytic solutions for marginal deformations satisfying the reality condition in open superstring field theory formulated by Berkovits when operator products made of the marginal operator and the associated superconformal primary field are regular. Our strategy is based on the recent observation by Erler that the problem of finding solutions for marginal deformations in open superstring field theory can be reduced to a problem in the bosonic theory of finding a finite gauge parameter for a certain pure-gauge configuration labeled by the parameter of the marginal deformation. We find a gauge transformation generated by a real gauge parameter which infinitesimally changes the deformation parameter and construct a finite gauge parameter by its path-ordered exponential. The resulting solution satisfies the reality condition by construction.

description: We search for a first-order phase transition gravitational wave signal in 45 pulsars from the NANOGrav 12.5 year dataset. We find that the data can be modeled in terms of a strong first order phase transition taking place at temperatures below the electroweak scale. However, we do not observe any strong preference for a phase-transition interpretation of the signal over the standard astrophysical interpretation in terms of supermassive black holes mergers; but we expect to gain additional discriminating power with future datasets, improving the signal to noise ratio and extending the sensitivity window to lower frequencies. An interesting open question is how well gravitational wave observatories could separate such signals.

description: The unprecedented ease and ability to manipulate video content has led to a rapid spread of manipulated media. The availability of video editing tools greatly increased in recent years, allowing one to easily generate photo-realistic alterations. Such manipulations can leave traces in the metadata embedded in video files. This metadata information can be used to determine video manipulations, brand of video recording device, the type of video editing tool, and other important evidence. In this paper, we focus on the metadata contained in the popular MP4 video wrapper/container. We describe our method for metadata extractor that uses the MP4's tree structure. Our approach for analyzing the video metadata produces a more compact representation. We will describe how we construct features from the metadata and then use dimensionality reduction and nearest neighbor classification for forensic analysis of a video file. Our approach allows one to visually inspect the distribution of metadata features and make decisions. The experimental results confirm that the performance of our approach surpasses other methods.

description: We show that, for a generic choice of a point on the Coulomb branch of any N=2 supersymmetric gauge theory, it is possible to find a superpotential perturbation which generates a metastable vacuum at the point. For theories with SU(N) gauge group, such a superpotential can be expressed as a sum of single-trace terms for N=2 and 3. If the metastable point is chosen at the origin of the moduli space, we can show that the superpotential can be a single-trace operator for any N. In both cases, the superpotential is a polynomial of degree 3N of the vector multiplet scalar field.

description: We propose to use the High Momentum Spectrometer of Hall C combined with the Neutral Particle Spectrometer (NPS) to perform high precision measurements of the Deeply Virtual Compton Scattering (DVCS) cross section using a beam of positrons. The combination of measurements with oppositely charged incident beams is the only unambiguous way to disentangle the contribution of the DVCS$^2$ term in the photon electroproduction cross section from its interference with the Bethe-Heitler amplitude. This provides a stronger way to constrain the Generalized Parton Distributions of the nucleon. A wide range of kinematics accessible with an 11 GeV beam off an unpolarized proton target will be covered. The $Q^2-$dependence of each contribution will be measured independently.

description: В статье исследуется кубическая модификация Mg 2 TiO 4 со структурой обратной шпинели. Вычисляются энергия элементарной ячейки и ширина запрещенной зоны для различных распределений атомов Mg и Ti по октаэдрическим позициям. Построена зависимость ширины запрещенной зоны как функция полной энергии элементарной ячейки. Показано, что высокосимметричное распределение атомов по октаэдрическим позициям приводит к переходу кристалла к тетрагональной симметрии с более низкой энергией по сравнению с кубическим кристаллом, для котрого характерно случайное распределение атомов.

description: We explore the constraints on the three-nucleon force (3NF) of chiral effective field theory ($χ$EFT) that are provided by bound-state observables in the $A=3$ and $A=4$ sectors. Our statistically rigorous analysis incorporates experimental error, computational method uncertainty, and the uncertainty due to truncation of the $χ$EFT expansion at next-to-next-to-leading order. A consistent solution for the ${}^3$H binding energy, the ${}^4$He binding energy and radius, and the ${}^3$H $β$-decay rate can only be obtained if $χ$EFT truncation errors are included in the analysis. All of these except the $β$-decay rate give essentially degenerate constraints on the 3NF low-energy constants, so it is crucial for estimating these parameters. We use eigenvector continuation for fast and accurate emulation of No-Core Shell Model calculations of the considered few-nucleon observables. This facilitates sampling of the posterior probability distribution, allowing us to also determine the distributions of the hyperparameters that quantify the truncation error. We find a $χ$EFT expansion parameter of $Q=0.33 \pm 0.06$ for these observables.

description: The distribution of galaxies in position and velocity around the centers of galaxy clusters encodes important information about cluster mass and structure. Using the maxBCG galaxy cluster catalog identified from imaging data obtained in the Sloan Digital Sky Survey, we study the BCG-galaxy velocity correlation function. By modeling its non-Gaussianity, we measure the mean and scatter in velocity dispersion at fixed richness. The mean velocity dispersion increases from 202+/-10 km/s for small groups to more than 854+/-102 km/s for large clusters. We show the scatter to be at most 40.5+/-3.5%, declining to 14.9+/-9.4% in the richest bins. We test our methods in the C4 cluster catalog, a spectroscopic cluster catalog produced from the Sloan Digital Sky Survey DR2 spectroscopic sample, and in mock galaxy catalogs constructed from N-body simulations. Our methods are robust, measuring the scatter to well within one-sigma of the true value, and the mean to within 10%, in the mock catalogs. By convolving the scatter in velocity dispersion at fixed richness with the observed richness space density function, we measure the velocity dispersion function of the maxBCG galaxy clusters. Although velocity dispersion and richness do not form a true mass-observable relation, the relationship between velocity dispersion and mass is theoretically well characterized and has low scatter. Thus our results provide a key link between theory and observations up to the velocity bias between dark matter and galaxies.

The effect of deformational mechanisms on the permeability of Upper Paleozoic limestone, dolostone and sandstone near Overfold Mountain, 55 kilometres southeast of Fernie, British Columbia
Creators: name: Hammack, Janet L.
Publisher: name: University of British Columbia
Year: 2010

description: Overfold Mountain is located approximately 55 km southeast of Fernie British Columbia in the MacDonald Range of the Rocky Mountains. In the area, limestones, dolostones and sandstones of the Upper Carboniferous Rundle Group and Rocky Mountain Group have been thrown into a series of northwesterly trending folds on the hanging wall of the Lewis Thrust sheet. This study focuses on the deformational mechanisms which have led to the development of one of these megascopic structures, with an emphasis on the role of permeability before, during and after deformation. Deformational mechanisms which have been active near Overfold Mountain include solution processes (pressure solution and hydraulic fracturing), shear fracturing, and intragranular mechanisms (mechanical twinning, dislocation glide, and microfracturing). How strain is partitioned between these mechanisms is largely governed by the permeability of the unit. Permeability is of primary importance in the determination of how a rock will respond in a nonhydrostatic stress field at low temperatures (<0.5 Tm). In the study area, carbonate rocks with a high initial permeability have accommodated strain by pressure solution. Carbonates and sandstones of low initial permeability have accommodated strain by shear fracturing and intragranular mechanisms. Finite permeability in the carbonates and sandstones of the study area, has been altered as a result of these deformational mechanisms. Units which had a high permeability prior to deformation have had their permeability blocked by pressure solution. Units which had a low permeability prior to deformation, have developed microfractures which have increased the finite permeability. This latter phenomenon is well illustrated in the dolostone units studied, both of which have a very well developed fracture porosity.

description: Effective low energy models arising in the context of D-brane configurations with Standard Model (SM) gauge symmetry extended by several gauged abelian factors are discussed. The models are classified according to their hypercharge embeddings consistent with the SM spectrum hypercharge assignment. Particular cases are analyzed according to their perspectives and viability as low energy effective field theory candidates. The resulting string scale is determined by means of a two-loop renormalization group calculation. Their implications in Yukawa couplings, neutrinos and flavor changing processes are also presented.

description: Programmable arrays of hundreds of Rydberg atoms have recently enabled the exploration of remarkable phenomena in many-body quantum physics. In addition, the development of high-fidelity quantum gates are making them promising architectures for the implementation of quantum circuits. We present here \textit{Pulser}, an open-source Python library for programming neutral-atom devices at the pulse level. The low-level nature of Pulser makes it a versatile framework for quantum control both in the digital and analog settings. The library also contains simulation routines for studying and exploring the outcome of pulse sequences for small systems.

title: The effectiveness of National Human Rights Institutions (NHRI)
title: towards establishing an effective NHRI in the UAE
titleType: Subtitle
Creators: name: Alnaqbi, Basim Hassan Ali Ibrahim Ahmed
Publisher: name: Lancaster University
Year: 2018

description: This is a case study on establishing a human rights institution in the UAE
      that would promote and disseminate the culture of human rights and
      fundamental freedoms in the country. The study argues that establishing a
      strong, politically independent, active and effective national human
      rights institution in the UAE sooner than later is of paramount
      importance. The research emphasises that this is the age of human rights
      and freedoms and a relevant mechanism to safeguard these freedoms should
      appear in the UAE. Human rights have become the norm and means of
      measurements of everyday life- business, politics, international relations
      and cooperations. In a nutshell, the UAE requires more debate, more
      serious studies on the issue, political dialogue and political consensus
      on its possible form, functions and a mandate of the new human rights
      institution. This study suggests that establishing a human rights
      institution to promote, protect, monitor and consolidate human rights and
      fundamental freedoms in the UAE is vital. As such organisations become the
      norm worldwide; the UAE cannot live in isolation.

      NHRIs are useful institution and can make an important contribution to the
      protection and promotion of human rights in the country. In this current
      climate, it becomes increasingly more vital to defend and protect
      established international human rights standards, challenge abuses of
      limit maladministration in public office and glitch demographics.
      Establishment of a new Human Rights institution in the UAE requires and
      demands a careful balance between traditional values, norms and
      established principles and changes. Otherwise, the newly found NHRI in the
      UAE would be prone to suffer from structural problems, functional
      deficiencies and may lack adequate mechanisms for enforcement of human
      rights. The time is now ripe to establish a human rights institution in
      the UAE to tackle the many challenges that the nation is facing in coming
      years, as highlighted by the international reports issued by international
      human rights organisations.

      This study suggests a human rights approach is a crucial tool to improve
      the current understanding of why the UAE need to establish a National
      Human Rights Institution and to describe the Human rights situation in its
      broader context. The challenges of the UAE’s human rights application and
      the need to consider a balanced approach incorporating a clear human
      rights perspective will be examined and critically evaluated throughout
      this thesis.
Numerical modelling of large scale toppling
Creators: name: Pritchard, Mark Anderson
Publisher: name: University of British Columbia
Year: 2010

description: The principle purpose of this research is to resolve the mode of failure of the Heather Hill landslide, one of several well defined failures in the Beaver Valley, Glacier National Park, British Columbia. Field work led to the preliminary conclusion that some type of toppling process contributed to the failure. A literature review of toppling revealed that large scale topples have never been quantitatively assessed, and that currently used analytical techniques are not adequate. Consideration of alternative numerical techniques resulted in the distinct element method being selected as the best technique for modelling toppling. The Universal Distinct Element Code (UDEC) was purchased and its suitability demonstrated by reevaluating examples of toppling analysis reported in the literature, and evaluating a large scale engineered slope at Brenda mine where toppling is known to occur. UDEC is used to examine and classify the mode of failure of the Heather Hill slide. This research leads to very important general conclusions on toppling and specific conclusions relating to the Heather Hill landslide: UDEC is suitable for modelling all types of topples. The program can be used to back analyze rock mass strength parameters and determine the shape and location of the final failure surface in flexural toppling. A quantitative assessment with UDEC confirms that the base of failure in flexural toppling may be planar or curvilinear, and that pore pressures significantly affect stability. The Heather Hill landslide failed by flexural toppling limiting to a curvilinear failure surface, and the slope immediately north of the Heather Hill landslide is deformed by flexural toppling. The locations of landslides in the Beaver Valley correspond with the occurrence of foliated pelitic rocks in the lower slopes and the boundary between these rocks and stronger grits is the up slope limit. The kinematic test of toppling potential is violated by the Heather Hill landslide. This test is shown to only apply to small scale drained slopes.

description: We study quantum Darwinism -- the redundant recording of information about a decohering system by its environment -- in zero-temperature quantum Brownian motion. An initially nonlocal quantum state leaves a record whose redundancy increases rapidly with its spatial extent. Significant delocalization (e.g., a Schroedinger's Cat state) causes high redundancy: many observers can measure the system's position without perturbing it. This explains the objective (i.e. classical) existence of einselected, decoherence-resistant pointer states of macroscopic objects.
