Abstract

We propose the decay modes B→a₀(→ηπ)π to determine the CKM phase α. One can analyze these modes through (i) the B→a₀π isospin pentagon, (ii) the time dependent Dalitz plot of B⁰(t)→a₀^±π^± →ηπ⁺π^-, and (iii) the time dependence of B⁰(t)→a₀⁰(→ηπ ⁰)π⁰. We show that the a₀π modes have certain advantages as compared to the ρπ modes, and strongly recommend the time dependent Dalitz plot analysis in the a₀π channel.
