Measurement of the W+W- cross section in pp collisions at √s= 8 TeV and limits on anomalous gauge couplings
(2016)The European Physical Journal CA measurement of the W boson pair production cross section in proton-proton collisions at s√=8 TeV is presented. The data collected with the CMS detector at the LHC correspond to an integrated luminosity of 19.4fb-1. The W+W− candidates are selected from events with two charged leptons, electrons or muons, and large missing transverse energy. The measured W+W− cross section is 60.1±0.9(stat)±3.2(exp)±3.1(theo)±1.6(lumi)\,pb=60.1±4.8\,pb, ...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. The results are based on pp collision data at a centre-of-mass energy of 8 TeV collected by the CMS experiment at the LHC and corresponding to an integrated luminosity of 19.7 fb−1. Pseudoscalar boson masses between 25 and 80 GeV are probed. No evidence for a ...Journal Article -
Search for heavy resonances decaying to two Higgs bosons in final states containing four b quarks
(2016)The European Physical Journal CA search is presented for narrow heavy resonances X decaying into pairs of Higgs bosons (H) in proton-proton collisions collected by the CMS experiment at the LHC at s√=8TeV. The data correspond to an integrated luminosity of 19.7fb−1. The search considers HH resonances with masses between 1 and 3TeV, having final states of two b quark pairs.

Measurement of inclusive jet production and nuclear modifications in pPb collisions at √sNN = 5.02 TeV
(2016)The European Physical Journal CInclusive jet production in pPb collisions at a nucleon–nucleon (NN) center-of-mass energy of sNN−−−√=5.02TeV is studied with the CMS detector at the LHC. A data sample corresponding to an integrated luminosity of 30.1 nb−1 is analyzed. The jet transverse momentum spectra are studied in seven pseudorapidity intervals covering the range −2.0<ηCM<1.5 in the NN center-of-mass frame. The jet production yields at forward and backward pseudorapidity ...Journal Article -
Search for supersymmetry in the multijet and missing transverse momentum final state in pp collisions at 13 TeV
(2016)Physics Letters BA search for new physics is performed based on all-hadronic events with large missing transverse momentum produced in proton–proton collisions at s=13 TeV. The data sample, corresponding to an integrated luminosity of 2.3 fb−1, was collected with the CMS detector at the CERN LHC in 2015. The data are examined in search regions of jet multiplicity, tagged bottom quark jet multiplicity, missing transverse momentum, and the scalar sum of jet ...Journal Article -
Measurement of spin correlations in tt production using the matrix element method in the muon+jets final state in pp collisions at √s=8 TeV
(2016)Physics Letters BThe consistency of the spin correlation strength in top quark pair production with the standard model (SM) prediction is tested in the muon+jets final state. The events are selected from pp collisions, collected by the CMS detector, at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19.7 fb−1. The data are compared with the expectation for the spin correlation predicted by the SM and with the expectation of ...Journal Article -
