Abstract

We study in detail semi-inclusive charmless B → πX decays such as B̄⁰ → π^±(0))X, B⁰ → π^±(0)X and B^± → π^±(0)X, where X does not contain a charm (anti)quark. We find that the process B̄⁰ → π^-X (B⁰ → π⁺X) can be particularly useful for the determination of the CKM matrix element |V_ub|. We calculate and present the branching ratio (BR) of B̄⁰ → π^-X as a function of |V_ub|, with an estimate of possible uncertainties. It is expected that the BR is of the order of 10^-4. Our estimation indicates that one can phenomenologically determine |V_ub| with a reasonable accuracy by measuring the BR of B̄⁰ → π^-X (B⁰ → π⁺X.
