Abstract

I compare collinear and $k_T$ factorization theorems in perturbative QCD, and discuss their application to exclusive $B$ meson decays. Especially, I concentrate on the recently measured time-dependent CP asymmetry of the $B^0_d\to\pi^+\pi^-$ modes, from which the unitarity angle can be extracted.
