title: "Table 27" of "Measurement of differential production cross-sections for a $Z$ boson in association with $b$-jets in 7 TeV proton-proton collisions with the ATLAS detector"

description: The cross-section $\sigma(Zbb)$ as a function of $Z$ boson $|y|$ together with the corresponding non-perturbative corrections.
description: CERN-LHC. Measurements of differential production cross-sections of a Z boson in association with b-jets in pp collisions at sqrt(s) = 7 TeV are reported. The data analysed correspond to an integrated luminosity of 4.6 fb^{-1} recorded in 2011 with the ATLAS detector at the Large Hadron Collider. Particle-level cross-sections are determined for events with a Z boson decaying into an electron or muon pair, and containing b-jets. For events with at least one b-jet, the cross-section is presented as a function of the Z boson transverse momentum and rapidity, together with the inclusive b-jet cross-section as a function of b-jet transverse momentum, rapidity and angular separations between the b-jet and the Z boson. For events with at least two b-jets, the cross-section is deter mined as a function of the invariant mass and angular separation of the two highest transverse momentum b-jets, and as a function of the Z boson transverse momentum and rapidity.

Theoretical non-perturbative corrections for the differential cross-sections are given in the tables below as multiplicative correction factors applied to parton-level theory predictions from MCFM to account for the softening of the jet spectra due to fragmentation and hadronisation and to the enhancement of the cross-section due to multi-parton interactions (MPI). A constant QED multiplicative factor, correcting the born lepton definition in MCFM to the dressed definition used in the analysis, is included. The various sources of uncertainties (MC sample size, differences between PYTHIA and SHERPA in the modelling of NP-QCD effects, QED final state radiation (FSR) correction and uncertainties on the modelling of the double parton interaction from a comparison to data) are listed separately.

title: Machine Learned Interatomic Potential: "Reactive hydrogenation of interstellar carbon monoxide ices. The viewpoint of machine learning-driven simulations"

description: The training set for creating the MLIP used to simulate the reactive hydrogenation of interstellar carbon monoxide ices is stored in "FINALMLIP.npz". The creation of this dataset as well as the experiments performed are hihglighted in the publication "Reactive hydrogenation of interstellar carbon monoxide ices. The viewpoint of machine learning-driven simulations". The dataset is stored in python compressed format (.npz) with the atomization eneriges in eV/mol and atomic forcs in eV/mol/Ang. The data set contains five numpy arrays:

import numpy as np

data=np.load("FINALMLIP.npz")

data['R'] # Cartesian coordinates of nuclei (Ang.)

data['E'] # Total energy (eV/mol)

data['F'] # Atomic forces (eV/mol/Ang.)

data['N'] # Number of atoms in each structure

data['Z'] # Nuclear charges

 

The accuracy of the potential is tested during applications. We compare the force and uncertainty norms during the formation of HCO in different simulations, noting that the force remains lower than 10% of the force norm. In that regard, the left and right axes of all plots are scaled in a 10:1 proportion. The experiments in each image are:

title: "Table 1" of "Measurement of charged particle multiplicities in $pp$ collisions at ${\sqrt{s} =7}$TeV in the forward region"

description: Charged particle multiplicity distribution in minimum bias events for different pseudorapidity bins. The first quoted uncertainty is statistical and the second is systematic.
description: CERN-LHC. 
Prompt charged particle production in proton-proton collisions is studied with the LHCb detector at a centre-of-mass energy of $\sqrt{s}=7$ TeV in different intervals of pseudorapidity: $-2.5 &lt; \eta &lt; -2.0$ and $2.0 &lt; \eta &lt; 4.5$. Two classes of events are selected by requiring at least one track in the full forward $\eta$ range for minimum bias events and at least one track with transverse momentum greater than 1 GeV/c in $2.5 &lt; \eta &lt; 4.5$ for a subsample of hard QCD events. Prompt charged particles are selected imposing a limit on the sum of the ancestors life time of 10 ps so that final state particles originating in $b$ and $c$ hadron decays are considered prompt. Charged particle multiplicity distributions in $\eta$ bins and in the full forward range for the two event classes are given. Also charged particle densities as function of $\eta$ are shown in the full pseudorapidity range.

title: "Table 1" of "Search for non-pointing and delayed photons in the diphoton and missing transverse momentum final state in 8 TeV $pp$ collisions at the LHC using the ATLAS detector"

description: Observed CLs contour in the GMSB (LAMBDA, TAU(NEUTRALINO) ) signal space.
description: CERN-LHC. A search has been performed, using the full data sample of 20.3 fb-1 of 8 TeV proton-proton collisions collected in 2012 with the ATLAS detector at the LHC, for photons originating from a displaced vertex due to the decay of a neutral long-lived particle into a photon and an invisible particle. The analysis investigates the diphoton plus missing transverse momentum final state, and is therefore most sensitive to pair-production of long-lived particles. The analysis technique exploits the capabilities of the ATLAS electromagnetic calorimeter to make precise measurements of the flight direction, as well as the time of flight, of photons. No excess is observed over the Standard Model predictions for background. Exclusion limits are set within the context of Gauge Mediated Supersymmetry Breaking models, with the lightest neutralino being the next-to-lightest supersymmetric particle and decaying into a photon and gravitino with a lifetime in the range from 250 ps up to about 100 ns.
