Measurement of differential cross sections for the production of a pair of isolated photons in pp collisions at √s=7 TeV
(2014)The European Physical Journal CA measurement of differential cross sections for the production of a pair of isolated photons in proton–proton collisions at √s=7TeV is presented. The data sample corresponds to an integrated luminosity of 5.0fb−1 collected with the CMS detector. A data-driven isolation template method is used to extract the prompt diphoton yield. The measured cross section for two isolated photons, with transverse energy above 40 and 25GeV respectively, ...Journal Article -
Search for heavy narrow dilepton resonances in pp collisions at √s=7 TeV and √s=8 TeV
(2013)Physics Letters BAn updated search for heavy narrow resonances decaying to muon or electron pairs using the CMS detector is presented. Data samples from pp collisions at s=7TeV and 8 TeV at the LHC, with integrated luminosities of up to 5.3 and 4.1fb−1, respectively, are combined. No evidence for a heavy narrow resonance is observed. The analysis of the combined data sets excludes, at 95% confidence level, a Sequential Standard Model ZSSM′ resonance lighter ...Journal Article -
Measurement of the total and differential inclusive B+ hadron cross sections in pp collisions at √s = 13 TeV
(2017)Physics Letters BThe differential cross sections for inclusive production of B+ hadrons are measured as a function of the B+ transverse momentum pTB and rapidity yB in pp collisions at a centre-of-mass energy of 13 TeV, using data collected by the CMS experiment that correspond to an integrated luminosity of 48.1 pb−1. The measurement uses the exclusive decay channel B+→J/ψK+, with J/ψ mesons that decay to a pair of muons. The results show a reasonable ...Journal Article -
Measurement of differential cross sections for Higgs boson production in the diphoton decay channel in pp collisions at √s = 8 TeV
(2016)The European Physical Journal CA measurement is presented of differential cross sections for Higgs boson (H) production in pp collisions at s√=8 TeV. The analysis exploits the H→γγ decay in data corresponding to an integrated luminosity of 19.7fb-1 collected by the CMS experiment at the LHC. The cross section is measured as a function of the kinematic properties of the diphoton system and of the associated jets. Results corrected for detector effects are compared with ...Journal Article -
Measurement of the top-quark mass in all-jets tt events in pp collisions at √s = 7 TeV
(2014)The European Physical Journal CThe mass of the top quark is measured using a sample of tt¯ candidate events with at least six jets in the final state. The sample is selected from data collected with the CMS detector in pp collisions at s√=7 TeV in 2011 and corresponds to an integrated luminosity of 3.54 fb−1. The mass is reconstructed for each event employing a kinematic fit of the jets to a tt¯ hypothesis. The top-quark mass is measured to be 173.49±0.69(stat.)±1.21(syst.) ...Journal Article -
Probing color coherence effects in pp collisions at √s = 7 TeV
(2014)The European Physical Journal CA study of color coherence effects in pp collisions at a center-of-mass energy of 7TeV is presented. The data used in the analysis were collected in 2010 with the CMS detector at the LHC and correspond to an integrated luminosity of 36 pb−1. Events are selected that contain at least three jets and where the two jets with the largest transverse momentum exhibit a back-to-back topology. The measured angular correlation between the second- ...Journal Article -
Measurement of the double-differential inclusive jet cross section in proton–proton collisions at √s = 13 TeV
(2016)The European Physical Journal CA measurement of the double-differential inclusive jet cross section as a function of jet transverse momentum pT and absolute jet rapidity |y| is presented. The analysis is based on proton–proton collisions collected by the CMS experiment at the LHC at a centre-of-mass energy of 13TeV. The data samples correspond to integrated luminosities of 71 and 44pb-1 for |y|<3 and 3.2<|y|<4.7, respectively. Jets are reconstructed with the anti-kt ...Journal Article -
Search for New Physics with Same-Sign Isolated Dilepton Events with Jets and Missing Transverse Energy
(2012)Physical ReviewA search for new physics is performed in events with two same-sign isolated leptons, hadronic jets, and missing transverse energy in the final state. The analysis is based on a data sample corresponding to an integrated luminosity of 4.98 fb−1 produced in pp collisions at a center-of-mass energy of 7 TeV collected by the CMS experiment at the LHC. This constitutes a factor of 140 increase in integrated luminosity over previously published ...Journal Article -
Search for top squark pair production in compressed-mass-spectrum scenarios in proton-proton collisions at √s = 8 TeV using the αT variable
(2017)Physics Letters BAn inclusive search is performed for supersymmetry in final states containing jets and an apparent imbalance in transverse momentum, p→Tmiss, due to the production of unobserved weakly interacting particles in pp collisions at a centre-of-mass energy of 8 TeV. The data, recorded with the CMS detector at the CERN LHC, correspond to an integrated luminosity of 18.5 fb−1. The dimensionless kinematic variable αTαT is used to discriminate ...Journal Article -
Search for a low-mass pseudoscalar Higgs boson produced in association with a bb pair in pp collisions at √s=8 TeV
(2016)Physics Letters BA search is reported for a light pseudoscalar Higgs boson decaying to a pair of τ leptons, produced in association with a bb‾ pair, in the context of two-Higgs-doublet models.

Pseudoscalar boson masses between 25 and 80 GeV are probed. No evidence for a ...Journal Article
