Rare radiative exclusive B decays in soft-collinear effective theory
Junegone Chay, Chul Kim
We consider rare radiative B decays such as B -> K^* gamma or B -> rho gamma in soft-collinear effective theory, and show that the decay amplitudes are factorized to all orders in…

Nonleptonic B decays into two light mesons in soft-collinear effective theory
Junegone Chay, Chul Kim
We consider nonleptonic B decays into two light mesons at leading order in soft-collinear effective theory, and show that the decay amplitudes are factorized to all orders in alpha…

Factorization of B decays into two light mesons in soft-collinear effective theory
Junegone Chay, Chul Kim
We show that the amplitudes for B decays into two light mesons at leading order in soft-collinear effective theory are factorized to all orders in alpha_s. We construct gauge-invar…
