Event shapes and azimuthal correlations in Z plus jets events in pp collisions at root s=7 TeV
(Elsevier, 2013-05-23)
Measurements of event shapes and azimuthal correlations are presented for events where a Z boson is produced in association with jets in proton-proton collisions. The data collected with the CMS detector at the CERN LHC ...
Search for supersymmetry with razor variables in pp collisions at root s=7 TeV
(American Physical Society, 2014-12-01)
The razor approach to search for R–parity conserving supersymmetric particles is described in detail. Two analyses are considered: an inclusive search for new heavy particle pairs decaying to final states with at least two ...
Measurement of the ratio B(t -> Wb)/B(t -> Wq) in pp collisions at root s=8 TeV
(Elsevier, 2014-09-07)
The ratio of the top-quark branching fractions R = B(t --> Wb)/B(t --> Wq), where the denominator includes the sum over all down-type quarks (q = b, s, d), is measured in the t (t) over bar dilepton final state with ...
Search for resonant t(t)over-bar production in proton-proton collisions at root s=8 TeV
(American Physical Society, 2016-01-01)
A search is performed for the production of heavy resonances decaying into top-antitop quark pairs in proton-proton collisions at s√=8 TeV. Data used for the analyses were collected with the CMS detector and correspond ...
Measurement of pseudorapidity distributions of charged particles in proton-proton collisions at root s=8 TeV by the CMS and TOTEM experiments
(Springer Nature, 2014-10)
Pseudorapidity ( ηη ) distributions of charged particles produced in proton–proton collisions at a centre-of-mass energy of 8 TeV TeV are measured in the ranges |η|<2.2|η|<2.2 and 5.3<|η|<6.45.3<|η|<6.4 covered by the ...
Nuclear effects on the transverse momentum spectra of charged particles in pPb collisions at root s(NN)=5.02 TeV
(Springer Nature, 2015-05)
Transverse momentum spectra of charged particles are measured by the CMS experiment at the CERN LHC in pPb collisions at sNN−−−√=5.02sNN=5.02 TeVTeV , in the range 0.4<pT<1200.4<pT<120 GeV/cGeV/c and pseudorapidity ...
Constraints on the Higgs boson width from off-shell production and decay to Z-boson pairs
(Elsevier, 2014-07-09)
Constraints are presented on the total width of the recently discovered Higgs boson, Gamma(H), using its relative on-shell and off-shell production and decay rates to a pair of Z bosons, where one Z boson decays to an ...
Search for displaced supersymmetry in events with an electron and a muon with large impact parameters
(American Physical Society, 2015-02-13)
A search for new long-lived particles decaying to leptons is presented using proton-proton collisions produced by the LHC at s√=8 TeV. Data used for the analysis were collected by the CMS detector and correspond to an ...
Measurement of associated production of vector bosons and top quark-antiquark pairs in pp collisions at root s=7 TeV
(American Physical Society, 2013-04-26)
The first measurement of vector-boson production associated with a top quark-antiquark pair in proton-proton collisions at root s = 7 TeV is presented. The results are based on a data set corresponding to an integrated ...
Measurement of the underlying event activity using charged-particle jets in proton-proton collisions at √s=2.76 TeV
(Springer International Publishing, 2015-09)
A measurement of the underlying event (UE) activity in proton-proton collisions is performed using events with charged-particle jets produced in the central pseudorapidity region (|η jet| < 2) and with transverse momentum ...
