Long Talk (20 mins) QFT: The Standard Model


Matthew Rowe (Edinburgh)


In the era of precision phenomenology, quantum electrodynamic (QED) effects are of increasing relevance. However traditional interpolating operators used for dispersive sum rule calculations do not conserve charge. We study QED corrections to leptonic B decays in a new manifestly gauge invariant formalism paying particular attention to large collinear logarithms. Using the same techniques we also can predict heavy meson isospin mass differences in a model independent way.
