All orders factorization and the Coulomb problem
Journal Article
·
· Physical Review. D.
In the limit of large nuclear charge, , or small lepton velocity, , Coulomb corrections to nuclear beta decay and related processes are enhanced as and become large or even nonperturbative (with the QED fine structure constant). We provide a constructive demonstration of factorization to all orders in perturbation theory for these processes and compute the all-orders hard and soft functions appearing in the factorization formula. We clarify the relationship between effective field theory amplitudes and historical treatments of beta decay in terms of a Fermi function. Published by the American Physical Society 2024
