Description:
Author(s): Marat Freytsis, Zoltan Ligeti, and Joshua T. Ruderman The ratio of the measured B ¯ → D ( * ) ℓ ν ¯ decay rates for ℓ = τ vs e , μ deviate from the standard model (SM) by about 4 σ . We show that the data are in tension with the SM, independent of form factor calculations, and we update the SM prediction for B ( B → X c τ ν ¯ ) / B ( B → X c ℓ ν ¯ ) . We classify the operators that can a… [Phys. Rev. D 92, 054018] Published Mon Sep 14, 2015
