Isospin asymmetry in B→K*μ+μ- using AdS/QCD
Abstract
We compute the isospin asymmetry distribution in the rare dileptonic decay B→K*μ+μ-, in the dimuon mass squared (q2) region below the J/Ψ resonance, using nonperturbative inputs as predicted by the anti-de Sitter/quantum chromodynamics correspondence and by sum rules. We predict a positive asymmetry at q2=0 which flips sign in the region q2∈[1,2] GeV2 to remain small (≤2%) and negative for larger q2. While our predictions are distinct as q2→0, they become hardly model-dependent q2≥4 GeV2. We compare our predictions to the most recent LHCb data.
