In the interaction (1) we have assumed that a w-meson inter-acts directly with ap,-meson. Of
the alternative assumptions con-cerning the mechanism of the decay, that in which the …

HE present paper examines the reaction of negatively charged p,-mesons with atomic nuclei

The differential transition probability for the radiative decay of a polarized μ meson with the
most general choice of coupling constants, is calculated and integrated over electron …

The mean lifetime of the neutral π-meson has been determined by measurements on the
'direct'electron pairs associated with nuclear disintegrations and due to an alternative mode …

A Universal Vector minus Axial Vector coupling for the Fermi interaction among four
