Search for the decay B[0 over s] → D[superscript *∓]π[superscript ±]
A search for the decay B[0 over s] → D[superscript *∓]π[superscript ±] is presented using a data sample corresponding to an integrated luminosity of 1.0 fb[superscript −1] of pp collisions collected by LHCb. This decay is expected to be mediated by a W-exchange diagram, with little contribution fro...

description | A search for the decay B[0 over s] → D[superscript *∓]π[superscript ±] is presented using a data sample corresponding to an integrated luminosity of 1.0 fb[superscript −1] of pp collisions collected by LHCb. This decay is expected to be mediated by a W-exchange diagram, with little contribution from rescattering processes, and therefore a measurement of the branching fraction will help us to understand the mechanism behind related decays such as B[0 over s] → π[superscript +]π[superscript −] and B[0 over s] → D[bar over D]. Systematic uncertainties are minimized by using B[superscript 0] → D[superscript *∓]π[superscript ±] as a normalization channel. We find no evidence for a signal, and set an upper limit on the branching fraction of B(B[0 over s] → D[superscript *∓]π[superscript ±]) < 6.1(7.8) × 10[superscript −6] at 90% (95%) confidence level. |
