摘要：
We present a new technique to extract information on the unitarity triangle from the study of B-s -> 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 y from B-s -> K pi pi. (c) 2006 Elsevier B.V.
