Measurement of R(D*): the ratio of branching fractions between B0 → D*-τ+ντ and B0 → D*-μ+νμ using three-prong hadronic τ decays. [R(D*) in this measurement = 0.291±0.019±0.029; LHCb average = 0.310±0.016±0.022] Yesterday, at the 15th Flavor Physics and CP violation conference in Prague (Czech Republic), and today at a seminar at CERN, the LHCb collaboration…
