摘要：I discuss a recent calculation of the radiative corrections for all K3 decay modes. I review a new
update of the determination of the isospin breaking parameter K
SU(2) using current information
on the electromagnetic contributions to the pseudoscalar masses. I compare the theoretical result
with an “experimental” determination of this parameter from K3 data.
