Magnetic Monopole Decay and Its Consequences

We return to further examination of the need for the existence of magnetic monopoles based on the decades old derivation [Sherman Frankel, Amer. Jour. of Physics, 44, 7, 683-6 1976], of both the monopole-charge force, vec(F) = eg(vec(r) * vec(v)/c)/r^3, as well as the Dirac angular momentum, vec(l_f) = eg hat(r), from P and T conservation alone, without any recourse whatsoever to Maxwell's Equations. The eg product also appeared in the charge conserving equation, deg/dt = 0 = edg/dt + gde/dt, and this paper examines the second possible solution, dg/dt = - de/dt, namely monopole decay, accounting for the non-observance of stable monopoles. It treats astrophysics and neutrino physics consequences and suggestions for experimental searches.
