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 ratio of the production cross sections times branching fractions of B c ± → J/ψπ ± and B± → J/ψK ± and B(B±c→J/ψπ±π±π∓)/B(B±c→J/ψπ±)B(Bc±→J/ψπ±π±π∓)/B(Bc±→J/ψπ±) in pp collisions at s√=7s=7 TeV
(Springer Science+Business Media, 2015-01)
The ratio of the production cross sections times branching fractions (σ(B±c)B(B±c→J/ψπ±))/(σ(B±)B(B±→J/ψK±))(σ(Bc±)B(Bc±→J/ψπ±))/(σ(B±)B(B±→J/ψK±)) is studied in proton-proton collisions at a center-of-mass energy of 7 ...
