Observation of the decay B+ → ψ(2S)ϕ(1020)K+ in pp collisions at s=8TeV
(2017-01-10)
The decay B+→ψ(2S)ϕ(1020)K+ is observed for the first time using data collected from pp collisions at s=8TeV by the CMS experiment at the LHC, corresponding to an integrated luminosity of 19.6fb−1. The branching fraction ...
Measurement of double-differential cross sections for top quark pair production in pp collisions at √s=8TeV and impact on parton distribution functions
(2017-07-11)
Normalized double-differential cross sections for top quark pair (t t ¯) production are measured in pp collisions at a centre-of-mass energy of 8TeV with the CMS experiment at the LHC. The analyzed data correspond to an ...
Searches for pair production of third-generation squarks in √s=13TeV pp collisions
(2017-05-18)
Searches are presented for direct production of top or bottom squark pairs in proton–proton collisions at the CERN LHC. Two searches, based on complementary techniques, are performed in all-jet final states that are ...
Measurement of differential cross sections for top quark pair production using the lepton+jets final state in proton-proton collisions at 13 TeV
(2017-05-01)
Differential and double-differential cross sections for the production of top quark pairs in proton-proton collisions at 13 TeV are measured as a function of jet multiplicity and of kinematic variables of the top quarks ...
Search for anomalous Wtb couplings and flavour-changing neutral currents in t-channel single top quark production in pp collisions at √s=7 and 8 TeV
(2017-02-07)
Single top quark events produced in the t channel are used to set limits on anomalous Wtb couplings and to search for top quark flavour-changing neutral current (FCNC) interactions. The data taken with the CMS detector at ...
Search for top quark decays via Higgs-boson-mediated flavor-changing neutral currents in pp collisions at √s=8 TeV
(2017-02-15)
A search is performed for Higgs-boson-mediated flavor-changing neutral currents in the decays of top quarks. The search is based on proton-proton collision data corresponding to an integrated luminosity of 19.7 fb−1 at a ...
Search for heavy neutrinos or third-generation leptoquarks in final states with two hadronically decaying τ leptons and two jets in proton-proton collisions at √s=13 TeV
(2017-03-14)
A search for new particles has been conducted using events with two high transverse momentum (pT) τ leptons that decay hadronically, at least two high-pT jets, and missing transverse energy from the τ lepton decays. The ...
Search for anomalous couplings in boosted WW/WZ→ℓνqq‾ production in proton–proton collisions at s=8 TeV
(2017-09-10)
This Letter presents a search for new physics manifested as anomalous triple gauge boson couplings in WW and WZ diboson production in proton–proton collisions. The search is performed using events containing a W boson that ...
Evidence for collectivity in pp collisions at the LHC
(2017-02-10)
Measurements of two- and multi-particle angular correlations in pp collisions at s=5,7, and 13TeV are presented as a function of charged-particle multiplicity. The data, corresponding to integrated luminosities of 1.0pb−1 ...
