Hunting the CKM weak phase with time-integrated Dalitz analyses of Bs -> K pi pi decays

High Energy Physics - Phenomenology 2008-11-26 v3

Abstract

We present a new technique to extract information on the Unitarity Triangle from the study of Bs -> K pi pi Dalitz plot. Using isospin symmetry and the possibility to access the decay amplitudes from Dalitz analyses, we propose a new strategy to extract the weak phase gamma from Bs to K pi pi.
