π → e#betta##betta# decay: Symmetry breaking and the role of quark masses
Description
Symmetry-breaking corrections to low-energy theorems for π → e#betta##betta# decay are discussed. In particular, chiral-symmetry-breaking effects, originating from the pion mass, are found to be small in correspondence to the magnitudes of current quark masses recently suggested. (author)
