Lowest-order radiative corrections to the pion-photon-photon vertex are calculated in the pseudoscalar $\ensuremath{\pi}N\overline{N}$ theory. Causal analysis of two- and three-particle exchange… Expand

The real photon decay, $\ensuremath{\gamma}\ensuremath{\rightarrow}\ensuremath{\nu}\overline{\ensuremath{\nu}}$, is calculated in strong magnetic fields ($H\ensuremath{\sim}{10}^{13}$ G) using a… Expand

Within the context of the nonrelativistic theory of dyons, we study a number of interrelated issues concerning the quantum formulation of magnetic charge. We begin by solving the two‐body Schrodinger… Expand
