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, ...
Measurement of the CP-violating phase ϕs in the Bs 0→J/ψϕ(1020)→μ+μ−K+K− channel in proton-proton collisions at s=13TeV
(Springer, 2021-05-10)
The CP -violating weak phase ϕs and the decay width difference ΔΓs between the light and heavy Bs 0 mass eigenstates are measured with the CMS detector at the LHC in a sample of 48500 reconstructed Bs 0→J/ψϕ(1020)→μ+μ−K+K− ...
Angular analysis of the decay B + → K ∗ (892) +µ +µ − in proton-proton collisions at √s = 8 TeV
(Springer, 2021-01-14)
Angular distributions of the decay B+→ K∗(892)+μ+μ− 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 ...
Measurement of b jet shapes in proton-proton collisions at s√ = 5.02 TeV
(Springer, 2021-05-07)
We present the first study of charged-hadron production associated with jets originating from b quarks in proton-proton collisions at a center-of-mass energy of 5.02 TeV. The data sample used in this study was collected ...
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 ...
