Measurement of the differential cross sections for top quark pair production as a function of kinematic event variables in pp collisions at √s = 7 and 8 TeV
(American Physical Society, 2016-09)
Measurements are reported of the normalized differential cross sections for top quark pair production with respect to four kinematic event variables: the missing transverse energy; the scalar sum of the jet transverse ...
Event generator tunes obtained from underlying event and multiparton scattering measurements
(Springer-Verlag, 2016-03)
New sets of parameters (“tunes”) for the underlying-event (UE) modelling of the pythia8, pythia6 and herwig++ Monte Carlo event generators are constructed using different parton distribution functions. Combined fits to CMS ...
Measurement of the top quark mass using proton-proton data at √(s) = 7 and 8 TeV
(American Physical Society, 2016-04)
A new set of measurements of the top quark mass are presented, based on the proton-proton data recorded by the CMS experiment at the LHC at
√s = 8 TeV responding to a luminosity of 19.7 fb[superscript −1]. The top quark ...
Search for anomalous single top quark production in association with a photon in pp collisions at √s = 8 TeV
(Springer-Verlag/SISSA, 2016-04)
The result of a search for flavor changing neutral currents (FCNC) through single top quark production in association with a photon is presented. The study is based on proton-proton collisions at a center-of-mass energy ...
Measurement of the charge asymmetry in top quark pair production in pp Collisions at √s=8 TeV using a template method
(American Physical Society, 2016-02)
The charge asymmetry in the production of top quark and antiquark pairs is measured in proton-proton collisions at a center-of-mass energy of 8 TeV. The data, corresponding to an integrated luminosity of 19.6 fb⁻¹, were ...
Search for W′ → tb in proton-proton collisions at √s = 8 TeV
(Springer Nature, 2016-02)
A search is performed for the production of a massive W′ boson decaying to a top and a bottom quark. The data analysed correspond to an integrated luminosity of 19.7 fb[superscript −1] collected with the CMS detector at ...
Study of B meson production in p + Pb collisions at √s[subscript NN] = 5.02 TeV using exclusive hadronic decays
(American Physical Society, 2016-01)
The production cross sections of the B[superscript +], B[superscript 0], and B[0 over s] mesons, and of their charge conjugates, are measured via exclusive hadronic decays in p + Pb collisions at the center-of-mass energy ...
Search for single production of scalar leptoquarks in proton-proton collisions at √s = 8 TeV
(American Physical Society (APS), 2016-02)
A search is presented for the production of both first- and second-generation scalar leptoquarks with a final state of either two electrons and one jet or two muons and one jet. The search is based on a data sample of ...
Search for long-lived charged particles in proton-proton collisions at √s=13 TeV
(American Physical Society (APS), 2016-12)
Results are presen ted of a search for heavy stable charged particles produced in proton-proton collisions at √s = 13 TeV using a data sample corresponding to an integrated luminosity of 2.5 fb- 1 collected in 2015 with ...
Phenomenological MSSM interpretation of CMS searches in pp collisions at √s=7 and 8 TeV
(Springer Nature, 2016-10)
Searches for new physics by the CMS collaboration are interpreted in the framework of the phenomenological minimal supersymmetric standard model (pMSSM). The data samples used in this study were collected at s=7 and 8 TeV ...
