摘要：

Rare B-meson decays induced by the Flavor-Changing Neutral Current b -> s(d) transitions provide a stringent test of the SM in physics of quark flavors. Being loop-induced in the SM, they are suppressed and effects of New Physics can increase substantially their decay widths. Here, we consider the rare decay B+ -> pi(+)tau(+)tau(-). We present its dilepton invariant-mass distribution and decay width calculated in the Effective Electroweak Hamiltonian approach for different types of the B -> pi formfactor parameterizations. The ratio of the tauonic to muonic decay widths, R-pi(tau/mu), is also theoretically predicted.
