摘要
We compute the isospin asymmetry distribution in the rare dileptonic decay B -> K*mu(+)mu(-), in the dimuon mass squared (q(2)) region below the J/Psi. resonance, using nonperturbative inputs as predicted by the anti-de Sitter/quantum chromodynamics correspondence and by sum rules. We predict a positive asymmetry at q(2) = 0 which flips sign in the region q(2) is an element of[1, 2] GeV2 to remain small (<= 2%) and negative for larger q(2). While our predictions are distinct as q(2) -> 0, they become hardly model-dependent q(2) >= 4 GeV2. We compare our predictions to the most recent LHCb data.
