Investigation of the semileptonic weak decays of B_((s)) to S (Scalar Meson) via light-cone QCD sum rules

摘要

In this paper, the semileptonic weak decay process of B _((s)) → S scalar mesons is investigated by using the light-cone QCD sum rules (LCSR) in the nonperturbative part. The corresponding transition matrix elements leading to form factors and the branching ratio of this process are determined.
