A template fitting technique for reconstructing the amplitude of signals produced by the lead tungstate crystals of the CMS electromagnetic calorimeter is described. This novel approach is designed to suppress the contribution to the signal of the increased number of out-of-time interactions per beam crossing following the reduction of the accelera

Measurements are presented of the reduction of signal output due to radiation damage for two types of plastic scintillator tiles used in the hadron endcap (HE) calorimeter of the CMS detector. The tiles were exposed to particles produced in proton-proton (pp) collisions at the CERN LHC with a center-of-mass energy of 13 TeV, corresponding to a deli

A search is conducted for a low-mass charged Higgs boson produced in a top quark decay and subsequently decaying into a charm and a strange quark. The data sample was recorded in proton-proton collisions at ffiffi s p ¼ 13 TeV by the CMS experiment at the LHC and corresponds to an integrated luminosity of 35.9 fb−1. The search is performed in th

The transverse momentum (pT) distributions of Lambda, Xi(-), and Omega(-) baryons, their antiparticles, and K-S(0) mesons are measured in proton-proton (pp) and proton-lead (pPb) collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV over a broad rapidity range. The data, corresponding to integrated luminosities of 40.2 nb(-1) and 15.6 m

The cross section of top quark pair production is measured in the t¯t → (`ν` )(τhντ )bb final state, where ¯ τh refers to the hadronic decays of the τ lepton, and ` is either an electron or a muon. The data sample corresponds to an integrated luminosity of 35.9 fb−1 collected in proton-proton collisions at √ s = 13 TeV with the CMS de

The production of W± bosons is studied in proton-lead (pPb) collisions at a nucleon-nucleon centreof-mass energy of √sNN = 8.16 TeV. Measurements are performed in the W± → μ±νμ channel using a data sample corresponding to an integrated luminosity of 173.4 ± 6.1 nb−1, collected by the CMS Collaboration at the LHC. The number of positive

The first study of charm quark diffusion with respect to the jet axis in heavy ion collisions is presented. The measurement is performed using jets with pjet T > 60 GeV=c and D0 mesons with pD T > 4 GeV=c in lead-lead (Pb-Pb) and proton-proton (pp) collisions at a nucleon-nucleon center-of-mass energy of ffiffiffiffiffiffiffi sNN p ¼ 5.02

The observation of the 0 b → J/ψφ decay is reported using proton-proton collision data collected at √s = 13 TeV by the CMS experiment at the LHC in 2018, corresponding to an integrated luminosity of 60 fb−1. The ratio of the branching fractions B(0 b → J/ψφ)/B(0 b → ψ(2S)) is measured to be (8.26 ± 0.90 (stat) ± 0.68 (syst) ± 0.11

Introduction: Knowledge insufficiency and late detection may contribute towards the growing number of incidence and mortality rate of breast cancer in Malaysia. The aim of this study was to identify the socio-demographic and level of knowledge, awareness and practice on breast cancer among staff nurses of SASMEC@IIUM, Kuantan, Pahang. Materials and

Background and Objective: Data on whether periodontal therapy affects serum CRP levels are inconclusive. The aim of this study was to determine if nonsurgical periodontal therapy has any effect on CRP and serum lipid levels in patients with advanced periodontitis. Material and Methods: Thirty-six systemically healthy patients, ‡ 40 years of age a
