In the framework of the perturbative QCD approach, we study the charmless pure weak annihilation Bc->KK decay and find that the branching ratio BR(Bc->KK) O(10^-7). This prediction is so tiny that the Bc->KK decay might be unmeasurable at the Large Hadron Collider.

  1. Enhanced Quark-Loop Contribution to Pure Annihilation Nonleptonic B-meson decays in PQCD approach

    hep-ph 2025-04 conditional novelty 5.0 of 10

    Quark-loop NLO corrections to pure annihilation B decays leave branching ratios nearly unchanged but significantly enhance direct and mixing-induced CP asymmetries, with Bd to phi phi reaching about -40 percent.
