[Journal Club] Three-body Decays of Bs-->K(Kpi) Meson

Zhi-Tian Zou

In 2019, the LHCb collaboration have reported their amplitude analysis of Bs-->KsKpi decays, where the data can be well described by the contributions from the intermediate resonances K*(892), K_0^*(1430) and K_2^*(1430).

In this work, the authors have investigated these quasi-two-body decays Bs-->K/ar{K} Kpi , and calculated the branching fractions and the CP asymmetries within the perturbative QCD approach based on the K_T factorization.
