Abstract

A recent LHCb measurement of the CP violating flavour specific asymmetry in B_s⁰ decays, \asls, is presented. This measurement is based on a data sample corresponding to an integrated luminosity of 1 fb^-1 of pp collisions at √(s) = 7 TeV, collected during the 2011 run of the LHC. The result is \asls = (-0.24 ± 0.54_{\rm stat} ± 0.33_{\rm syst})× 10^-2, which is the most precise measurement of this quantity to date and agrees with the Standard Model prediction.
