Measurement of the Proper Time Resolution for $B \rightarrow h^{+} h^{' -}$ Channels from Data

A method to determine the parameters of the proper time resolution model for $B ightarrow h^+ h^{' -}$ channels at LHCb is described. The method uses only information which will be available from data. The resolution model is an important input to the fit which extracts the CKM angle $gamma$ fr...

description A method to determine the parameters of the proper time resolution model for $B ightarrow h^+ h^{' -}$ channels at LHCb is described. The method uses only information which will be available from data. The resolution model is an important input to the fit which extracts the CKM angle $gamma$ from the channels $B_d ightarrow pi^+ pi^-$ and $B_s ightarrow K^+ K^-$. It is found that with one nominal year of LHCb data, non-trivial constraints can be found for both the parameters of the resolution model, and the background to signal ratios.
