Abstract

We calculate the branching ratios and CP asymmetries of the B→ ϕK decays using perturbative QCD approach, which includes k_T and threshold resummations. Our results of branching ratios are consistent with the experimental data and larger than those obtained from the naive factorization assumption and the QCD-improved factorization approach.
