Measurement of the ratio B(t - GT Wb)/B(t - GT Wq) in pp collisions at root s=8 TeV
(Physics Letters B, 2014)
The ratio of the top-quark branching fractions R = B(t -- GT Wb)/B(t -- GT 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 ...
Measurement of the W boson helicity fractions in the decays of top quark pairs to lepton plus jets final states produced in pp collisions at root s=8 TeV
(Physics Letters B, 2016)
The W boson helicity fractions from top quark decays in t (t) over bar events are measured using data from proton-proton collisions at a centre-of-mass energy of 8 TeV. The data were collected in 2012 with the CMS detector ...
Search for a standard model-like Higgs boson in the mu(+)mu(-) and e(+)e(-) decay channels at the LHC
(Physics Letters B, 2015)
A search is presented for a standard model-like Higgs boson decaying to the mu(+)mu(-) or e(+)e(-) final states based on proton-proton collisions recorded by the CMS experiment at the CERN LHC. The data correspond to ...
Search for W decaying to tau lepton and neutrino in proton-proton collisions at root s=8 TeV
(Physics Letters B, 2016)
The first search for a heavy charged vector boson in the final state with a tau lepton and a neutrino is reported, using 19.7 fb(-1) of LHC data at root s = 8 TeV. A signal would appear as an excess of events with high ...
Search for stealth supersymmetry in events with jets, either photons or leptons, and low missing transverse momentum in pp collisions at 8 TeV
(Physics Letters B, 2015)
The results of a search for new physics in final states with jets, either photons or leptons, and low missing transverse momentum are reported. The study is based on a sample of proton-proton collisions collected at a ...
Long-range two-particle correlations of strange hadrons with charged particles in pPb and PbPb collisions at LHC energies
(Physics Letters B, 2015)
Measurements of two-particle angular correlations between an identified strange hadron (K-S(0) or A/(A) over bar) and a charged particle, emitted in pPb collisions, are presented over a wide range in pseudorapidity and ...
Measurement of spin correlations in tf production using the matrix element method in the muon plus jets final state in pp collisions at root S=8 TeV
(Physics Letters B, 2016)
The 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 ...
Search for supersymmetry in the multijet and missing transverse momentum final state in pp collisions at 13 TeV
(Physics Letters B, 2016)
A search for new physics is performed based on all-hadronic events with large missing transverse momentum produced in proton-proton collisions at root s = 13 TeV. The data sample, corresponding to an integrated luminosity ...
Measurement of the pp - GT ZZ production cross section and constraints on anomalous triple gauge couplings in four-lepton final states at root s=8 TeV
(Physics Letters B, 2015)
A measurement of the inclusive ZZ production cross section and constraints on anomalous triple gauge couplings in proton-proton collisions at root s = 8 TeV are presented. The analysis is based on a data sample, corresponding ...
Search for new phenomena in monophoton final states in proton-proton collisions at root s=8 TeV
(Physics Letters B, 2016)
Results are presented from a search for new physics in final states containing a photon and missing transverse momentum. The data correspond to an integrated luminosity of 19.6 fb(-1) collected in proton-proton collisions ...
