Sensitivity to the CKM Angle gamma with $B \to D(KK\pi\pi)K$ Decays at LHCb

An extension to the conventional Dalitz plot analysis of B->DK decays has recently been proposed where four-body final states of the D meson are considered. Such a method holds great potential for use at hadron collider experiments, like LHCb, when final states involving only charged tracks are c...

description An extension to the conventional Dalitz plot analysis of B->DK decays has recently been proposed where four-body final states of the D meson are considered. Such a method holds great potential for use at hadron collider experiments, like LHCb, when final states involving only charged tracks are considered. Following the results of an LHCb specific selection study of B->D(KKpipi)K decays, we now incorporate the corresponding signal yields and background estimates into a combined sensitivity study. With a 2fb^-1 data set and assuming a value of 0.10 for the parameter rB, we demonstrate that a sensitivity on gamma of approximately 18 degrees is achievable at LHCb.
