Abstract

Meson momentum-eigenstates are obtained by projecting from the boosted-bag model states. These momentum-eigenstates are then used to calculate the pion decay constant fn, and the weak pion-kaon transition matrix elements <π|Hω|K>. The transition matrix elements are parametrized to explain K → 2π decays and used to estimate the amplitude for rare decays K → πYy involving a light vector particle Yy.
