A Study of the Sensitivity to the Forward-Backward Asymmetry in $B_d \to K^{*} \mu^+ mu^-$ Decays at LHCb

The LHCb sensitivity to the zero-crossing point of the forward-backward asymmetry in the decay "Bd -> K*0 mu+ mu-" is presented. In the absence of background, a 2 fb^-1 data set will allow the zero-crossing point to be determined to a precision of 0.41 GeV^2/c^4. With the background add...

description The LHCb sensitivity to the zero-crossing point of the forward-backward asymmetry in the decay "Bd -> K*0 mu+ mu-" is presented. In the absence of background, a 2 fb^-1 data set will allow the zero-crossing point to be determined to a precision of 0.41 GeV^2/c^4. With the background added at the expected level, the expected precision is 0.46 GeV^2/c^4. With a 10 fb^-1 data set the resolutions improve to 0.25 (no background) and 0.27 GeV^2/c^4 (with background).
