Polarization fractions and helicity-dependent CP asymmetries in $B_{(s)}\to \rho \rho ,\rho K^{\ast }$ and $K^{\ast }{K}^{\ast }$ decays

Jian Chai, Shan Cheng, Feng-Qing Hu +3

In this paper, we present a phenomenological analysis of $B_{(s)}\to \rho \rho ,\rho K^{\ast }$ and $K^{\ast }{K}^{\ast }$ decays using state-of-the-art perturbative QCD (pQCD) calculations. Our study…
