Search for dark matter produced in association with heavy-flavor quark pairs in proton-proton collisions at √s=13TeV
(2017)The European Physical Journal CA search is presented for an excess of events with heavy-flavor quark pairs (tt¯ and bb¯¯) and a large imbalance in transverse momentum in data from proton–proton collisions at a center-of-mass energy of 13TeV. The data correspond to an integrated luminosity of 2.2fb−1 collected with the CMS detector at the CERN LHC. No deviations are observed with respect to standard model predictions. The results are used in the first interpretation of ...Journal Article -
Measurement of charged pion, kaon, and proton production in proton-proton collisions at √s=13 TeV
(2017)Physical Review DTransverse momentum spectra of charged pions, kaons, and protons are measured in proton-proton collisions at √s=13 TeV with the CMS detector at the LHC. The particles, identified via their energy loss in the silicon tracker, are measured in the transverse momentum range of pT≈0.1–1.7 GeV/c and rapidities |y|<1. The pT spectra and integrated yields are compared to previous results at smaller √s and to predictions of Monte Carlo event ...Journal Article -
Search for black holes and other new phenomena in high-multiplicity final states in proton–proton collisions at √s = 13 TeV
(2017)Physics Letters BA search for new physics in energetic, high-multiplicity final states has been performed using proton–proton collision data collected with the CMS detector at a center-of-mass energy of 13TeV and corresponding to an integrated luminosity of 2.3fb-1. The standard model background, dominated by multijet production, is determined exclusively from control regions in data. No statistically significant excess of events is observed. Model-independent ...Journal Article -
Combination of searches for heavy resonances decaying to WW, WZ, ZZ, WH, and ZH boson pairs in proton–proton collisions at s√=8 and 13 TeV
(2017)Physics Letters BA statistical combination of searches is presented for massive resonances decaying to WW, WZ, ZZ, WH, and ZH boson pairs in proton-proton collision data collected by the CMS experiment at the LHC. The data were taken at centre-of-mass energies of 8 and 13TeV, corresponding to respective integrated luminosities of 19.7 and up to 2.7 fb(-1). The results are interpreted in the context of heavy vector triplet and singlet models that mimic ...Journal Article -
Measurements of the associated production of a Z boson and b jets in pp collisions at √s = 8 TeV
(2017)The European Physical Journal CMeasurements of the associated production of a Z boson with at least one jet originating from a b quark in proton–proton collisions at √s=8TeV are presented. Differential cross sections are measured with data collected by the CMS experiment corresponding to an integrated luminosity of 19.8fb−1. Z bosons are reconstructed through their decays to electrons and muons. Cross sections are measured as a function of observables characterizing ...Journal Article -
Measurement of the triple-differential dijet cross section in proton-proton collisions at √s=8TeV and constraints on parton distribution functions
(2017)The European Physical Journal CA measurement is presented of the triple-differential dijet cross section at a centre-of-mass energy of 8TeV using 19.7fb-1 of data collected with the CMS detector in proton-proton collisions at the LHC. The cross section is measured as a function of the average transverse momentum, half the rapidity separation, and the boost of the two leading jets in the event. The cross section is corrected for detector effects and compared to calculations ...Journal Article -
Search for pair production of vector-like T and B quarks in single-lepton final states using boosted jet substructure in proton-proton collisions at s√=13 TeV
(2017)Journal of High Energy PhysicsA search for pair production of massive vector-like T and B quarks in proton-proton collisions at s√=13 TeV is presented. The data set was collected in 2015 by the CMS experiment at the LHC and corresponds to an integrated luminosity of up to 2.6 fb−1. The T and B quarks are assumed to decay through three possible channels into a heavy boson (either a W, Z or Higgs boson) and a third generation quark. This search is performed in final ...Journal Article -

Search for new phenomena with the MT2 variable in the all-hadronic final state produced in proton–proton collisions at √s=13 TeV
(2017)The European Physical Journal CA search for new phenomena is performed using events with jets and significant transverse momentum imbalance, as inferred through the MT2 variable.

No excess event yield is observed above the predicted standard model background, and the results ...Journal Article
