Measurement of the Λ b cross section and the Λ- b to Λ b ratio with J/ψΛ decays in pp collisions at s=7 TeV
- Abstract:
-
The Λ b differential production cross section and the cross section ratio σ(Λ-b)/σ(Λb) are measured as functions of transverse momentum pTΛb and rapidity |y Λb| in pp collisions at s=7 TeV using data collected by the CMS experiment at the LHC. The measurements are based on Λ b decays reconstructed in the exclusive final state J/ψΛ, with the subsequent decays J/ψ→μ +μ - and Λ→pπ, using a data sample corresponding to an integrated luminosity of 1.9 fb -1. The product σ(Λb)×B(Λb→J/ψΛ) versus pTΛ...
