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, ~ F = eg(~r × ~v/c)/r, as well as the Dirac angular momentum , ~lf = egr̂, 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.
