Abstract
We propose the decay modes B-->a(0)(-->eta pi)pi to determine the CKM phase alpha. One can analyze these modes through (i) the B-->a(0)pi isospin pent agon, (ii) the time dependent Dalitz plot of B-0(t)-->a(0)(+/-)pi (+/-) --> eta pi (+)pi (-), and (iii) the time dependence of B-0(t) --> a(0)(0)(-->et a pi (0))pi (0). We show that the a(0)pi modes have certain advantages as c ompared to the rho pi modes, and strongly recommend the time dependent Dali tz plot analysis in the a(0)pi channel.
