Reinvestigating B → PV decays by including contributions from ϕ B2 with the perturbative QCD approach *

Abstract

Abstract Considering the B mesonic wave function , decays are restudied in the leading order for three scenarios using the perturbative QCD approach within the standard model, where and K, and V denotes the ground vector mesons. It is found that contributions from can enhance most branching ratios and are helpful for improving the overall consistency of branching ratios between the updated calculations and available data, although there are still several discrepancies between the experimental and theoretical results.
