Branching ratio for B -> K_1 gamma decay in next-to-leading order in LEET

Abstract

Branching ratio for B -> K_1 gamma at next-to-leading order of alpha_s has been calculated in Large Energy Effective Theory. By incorporating the higher twist effects in light cone decay amplitude for axial K-meson, it is shown that the form factor is not sensitive to these twists.
