Heavy-to-light form factors of B decays at large recoil
Lee, Jong-Phil
Original · EN
The form factors of B→π(ρ) decays are analyzed using the light-cone sum rules in the framework of the soft-collinear effective theory (SCET). We establish the sum rules for the leading and the next-to-leading order (NLO) nonperturbative functions of the SCET. Explicit calculation shows that (leading)+(NLO) 1/E²+1/E³, where E is the large recoiling energy. The results are compatible with the literatures. Also the validity of this hybrid formalism is discussed.
