• #### 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±) in pp collisions at s√=7 TeV ﻿

(2015)
The ratio of the production cross sections times branching fractions (σ(B±c)B(B±c→J/ψπ±))/(σ(B±)B(B±→J/ψK±)) is studied in proton-proton collisions at a center-of-mass energy of 7 TeV with the CMS detector at the LHC. The ...
