B*q→DqV 和 PqD*非轻弱衰变的研究
Study of Nonleptonic B*q →Dq Vand Pq D*Weak Decays
摘要
Abstract
Motivated by the experiments of heavy flavor physics at running LHC and upgrading Belle-II in the future,the nonleptonic B-* →DD-* ,Dρ- ,DK*- ,πD* and KD* weak decays were studied in details.With the amplitudes calculated with factorization approach and the form factors of B* ransition into pseudoscalar mes-on evaluated with the BSW model,the branching fractions and the polarization fractions were firstly presented. Numerically,the B-*q → Dq Ds *- and Dqρ- decays had the large branching fractions,10 -8 ,which should be sought for with priority and firstly observed by LHC and Belle-II experiments.关键词
