A tricky method for indirect measurement of electron Antineutrino mass

During beta decay of rest neutron,

neutron beta decay

an electron anti neutrino is also emitted.

$n_o\to p^++e^-+ \overline\nu_e$

by detecting momentum of proton and electron after decay and by using conservation laws of einstein’s theory of relativity, i realized (indirectly) that electron anti neutrino is photon-like particle

$E= \vec {P}c=\vec {P_e}c=\vec {P_p}c$

and mass of Antineutrino is

$\overline \nu_e=\frac {E}{c^2} =0.545626\frac {Mev}{c^2}$

Essential Results:

$n_o=E_p+E_e +(E=\vec{P}c)=\sqrt{\vec{P_p} ^2c^2+p_o^2}+\sqrt{\vec{P_e} ^2c^2+e_o^2}+ E_{\overline \nu_e}$

where the $p_o$ denotes Energy of rest proton and $e_o$ denotes Energy of rest electron. $(E=\vec{P}c)$ denotes photon- like anti-neutrino.

$\alpha_w=\frac {\vec{P_e}c}{E_e}=\frac{1} {1.370073665}$

This is electron weak-structure constant (it is almost $100.0$ times stronger than fine-structure constant).
