• #### Measurement of prompt J/ψ pair production in pp collisions at √s = 7 Tev ﻿

(2014)
Production of prompt J/ψ meson pairs in proton-proton collisions at √s = 7 TeV is measured with the CMS experiment at the LHC in a data sample corresponding to an integrated luminosity of about 4.7 fb−1. The two J/ψ mesons ...
• #### 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 ...
• #### Measurement of the Λb cross section and the Λ¯b to Λb ratio with J/ψΛ decays in pp collisions at √s=7 TeV ﻿

(2012)
The Λb differential production cross section and the cross section ratio σ(Λ¯b)/σ(Λb) are measured as functions of transverse momentum pTΛb and rapidity |yΛb| in pp collisions at √s=7 TeV using data collected by the CMS ...
