Van de Water, and Ran Zhou (Fermilab Lattice and MILC Collaborations) The rare decay B → π ℓ + ℓ − arises from b → d flavor-changing neutral currents and could be sensitive to physics beyond the standard model. Here, we present the first ab initio QCD calculation of the B → π tensor form factor f T . Together with the vector and scalar form factors f + and f 0 from our companion wo… [Phys. Rev.
