Evaluation of B_sarrow D_s^-π^+ yield relative to B_darrow D^-π^+ and B_uarrow J/ψ K
Abstract
The new impact parameter trigger, SVT, allows CDF to collect samples of hadronic B decays. Several well known process like B_darrow D^-π^+ and B_uarrow J/ψ K have been already reconstructed with the twofold purpose: to characterize the trigger performances and to give a normalization for the study of new B decays. The process B_sarrow D_s^-π^+ can be studied for the first time at CDF and it is expected to give the largest contribution to the hadronic Bs data sample. We present here a study of σotBR(B_sarrow D_s^-π^+), comparing it to σotBR(B_darrow D^-π^+) and to σotBR(B_uarrow J/ψ K) where Ds is reconstructed through the decays in φπ (φarrow KK) and 3π.
