Branching fraction of the decay B+ → π+τ+τ− and lepton flavor universality test via the ratio Rπ(τ/μ)

Among (semi)leptonic rare B-decays induced by the b→d flavor changing neutral current, the decay B+→π+μ+μ− is the only one observed so far experimentally. Related decays involving the e+e− and τ+τ− pairs are the targets for the ongoing experiments at the LHC, in particular LHCb, and Belle II. The mu...
