The problem with an expression like,
Fh=Fsin(θ)=qpq4πεor2sin(θ)
from the post "Not This Way", is that qp don't exist.
Even if the photon is a dipole, its net charge from afar is zero.
There is one other possibility, that is for the matter-antimatter annihilation process to be slow. That popular literature on explosive matter/anti-matter reaction may not be true. Take the case of a hydrogen atom, when the electron collide into the proton nucleus,
the rate of annihilation along the charge-time line is,
Ea=dqdt=d(qpr+qe)dt=dmdt=d(mpr+me)dt
And Ea is slow. The reside charge on each of the particles forms a dipole and the energy released from E=mc2 make this both a very hot particle and a electric dipole. This is a H plasma particle, pp, that is experiencing a observable decay. What would its decay half life, ppT be? This hot dipole is a likely candidate for photon, both mechanisms for acceleration to light speed/terminal speed (as a dipole or hot particle) can apply to this particle.
Moreover since,
d(qpr+qe)dt=d(mpr+me)dt
we have a charge mass equivalence,
∫0qpr+qe1.dq=∫mpr−mempr+me1.dm
−(qpr+qe)=−2me and qpr=qe
we should have,
qe=me
the resulting neutral hot particle has mass mpr−me , likely a neutron. In this instance, both mass and charge are treated as inertia whether they are on the positive or negative time line. We also have,
qpr=me
that all the positive charge in a proton is from a mass of me.
It is more likely,
qe=Mcme where Mc is a scaling factor that also adjust for unit dimension, ie charge per unit mass, C kg-1.
