Radiative Corrections for Intensity Frontier Experiments

The proposal applies recent effective field theory advances to intensity frontier experiments at Fermilab. Applications include: the implementation of Coulomb- enhanced radiative corrections for accelerator neutrino cross sections; computing radiative corrections to enable a new low-energy search strategy at Mu2e; computing reactor neutrino fluxes using new quantum field theory constraints on the Fermi function for beta decay; computing radiative corrections to semileptonic B decays to enable precision lattice QCD to match experimental precision.
