Angular analysis of the decay B+ ? K?(892)+ ? + ? ? in proton-proton collisions at ?s = 8 TeV
(Springer Science and Business Media Deutschland GmbH, 2021)Angular distributions of the decay B+? K?(892)+?+?? are studied using events collected with the CMS detector in s = 8 TeV proton-proton collisions at the LHC, corresponding to an integrated luminosity of 20.0 fb?1. The ... -
Investigation into the event-activity dependence of gamma(nS) relative production in proton-proton collisions at root s=7 TeV
(Springer, 2020)The ratios of the production cross sections between the excited gamma(2S) and gamma(3S) mesons and the gamma(1S) ground state, detected via their decay into two muons, are studied as a function of the number of charged ... -
Measurement of properties of B(s)(0)s -> mu(+)mu(-) decays and search for B-0 -> mu(+)mu(-) with the CMS experiment
(Springer, 2020)Results are reported for the B 0s ! + branching fraction and effective lifetime and from a search for the decay B0 ! + . The analysis uses a data sample of proton-proton collisions accumulated by the CMS experiment in 2011, ... -
Observation of the decay B+ -> psi(2S)phi(1020)K+ in pp collisions at root s=8 TeV
(Elsevier, 2017)The decay B+ -> psi(2S) phi(1020) K+ is observed for the first time using data collected from pp collisions at root S = 8 TeV by the CMS experiment at the LHC, corresponding to an integrated luminosity of 19.6 fb(-1). The ... -
Observation of the Lambda(0)(b) -> J/psi Lambda phi decay in proton-proton collisions at root s=13 TeV
(Elsevier, 2020)The observation of the Lambda(0)(b) -> J/psi Lambda phi decay is reported using proton-proton collision data collected at root s = 13TeV by the CMS experiment at the LHC in 2018, corresponding to an integrated luminosity ... -
Search for flavor-changing neutral current interactions of the top quark and the Higgs boson decaying to a bottom quark-antiquark pair at root s=13 TeV
(Springer, 2022)A search for flavor-changing neutral current interactions of the top quark (t) and the Higgs boson (H) is presented. The search is based on a data sample corresponding to an integrated luminosity of 137 fb(-1) recorded by ... -
Study of the B+ -> J/psi(Lambda)over-barp decay in proton-proton collisions at root s=8 TeV
(Springer, 2019)A study of the B+-> J/psi = 8 TeV by the CMS experiment at the LHC, corresponding to an integrated luminosity of 19.6 fb(-1), is presented. The ratio of branching fractions B+-> J/psi B+-> J/psi K is measured to be (1.054 ...
