Phenomenological application of K(sub T)-factorization: Large direct CP-asymmetry in B-meson decays

Abstract

Applications of the perturbative QCD approach in the exclusive non-leptonic two body B-meson decays are discussed. Briefly reviewed are its ingredients and some important theoretical issues on the factorization approaches. PQCD results are compatible with present experimental data for the charmless B-meson decays. The possibility of large direct CP asymmetry is predicted in B(0) to pi(+)pi(-) (23 +/- 7 percent) and B(0) to K(+)pi(-) (- 17 +/- 5 percent). Also investigated are the Branching ratios, CP asymmetry and isospin symmetry breaking in B to (K(sup *)/rho)gamma decays and the possible new physics contribution is looked for via gluino mediation SUSY which can accommodate the large deviation of S(sub phiK(sub S)) from SM.
