Investigation into the event-activity dependence of ϒ(nS) relative production in proton-proton collisions at s√ = 7 TeV
(Springer Nature, 2020-11-02)
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 0 s → µ + µ − decays and search for B 0 → µ + µ − with the CMS experiment
(Springer Nature, 2020-04-28)
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 Λb 0→J/ψΛϕ decay in proton-proton collisions at √s=13 TeV
(Elsevier, 2020-03-10)
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 ...
