Given that a positron decay involves a proton being converted to a neutron (apparent gain in mass) while a small positive charge (positive electric potential) is released.
It is likely that,
the particle on the right with energy oscillating in the \(t_c\) time dimension is a negative gravity particle and the particle on left with energy oscillating in the \(t_T\) time dimension is a positive gravity particle.
Beta emissions allows for both proton to neutron and neutron to proton change and is not indicative here. But we see that, when a positive gravity particle is accelerated to light speed, \(x\to c\) and \(t_g\to0\), it is an electron. High energy positive gravity particles could be the beta particles detected during radioactive decays. On the other hand, when a negative gravity particle is accelerated, it becomes like a temperature particle with energy oscillating in \(t_c\).
When a positive gravity particle leave the atom, the binding energy at the nucleus due to negative gravity particles remains intact. There is however an apparent loss in mass.
Just a guess.
