Abstract: We analyze the quasi-two-body decays B+→π+ρ(770,1450)0→π+K+K- in the perturbative QCD approach. The results in this work do not support that large branching fractions contributed by the resonances ρ(770,1450)0 in the B±→π±K+K- decays. The virtual contribution… read more here.

Abstract: The widths of the τ → [ρ0(770), ρ0(1450)]π−ντ decays have been calculated within the extended Nambu—Jona-Lasinio model including both the ground and first radially excited intermediate meson states. The axial-vector channel with intermediate a1 mesons… read more here.
