Abstract

In the framework of the perturbative QCD approach, we study the charmless pure weak annihilation B_c^\ensuremath-\ensuremath→K^\ensuremath-K⁰ decay and find that the branching ratio BR(B_c\ensuremath→KK)\ensuremath∼O(10^\ensuremath-7). This prediction is so tiny that the B_c\ensuremath→KK decay might be unmeasurable at the Large Hadron Collider.
