On Vud determination from neutron decay
Abstract
The recent results of the PIBETA experiment strongly suggest the presence of a non-(V-A) anomalous interaction in the radiative pion decay. The same interaction should inevitably contribute to the neutron decay and in particular it should affect the Vud determination. This paper is dedicated to the prediction of the eventual discrepancy in Vud extracted from the super-allowed Fermi transitions and from the polarized neutron decay.
