## Main Question or Discussion Point

I am inquiring if anyone here is qualified to numerically demonstrate the solution to this equation?

The equation is the Proton lifetime derived from the SU(5) Georgi-Glashow model listed in reference 1, eq. (19).

SU(5) Proton lifetime:

[tex]\tau_p \geq \frac{1}{\alpha_{(5)}^2} \frac{M_X^4}{m_p^5}[/tex]

[tex]\tau_p \geq 10^{30} \; \text{years}[/tex]

According to reference 1, the parameters are:

[tex]m_p \geq 0.9382 \; \text{GeV}[/tex] - Proton mass

[tex]M_X \geq 10^{14} \; \text{GeV}[/tex] - X Boson mass

[tex]\alpha_{(5)} = \; \text{???}[/tex] - SU(5) fine structure consant

Experimentally observed values:

[tex]\tau_p \geq 10^{32} \; \text{years}[/tex] - (1990)

[tex]\tau_p \geq 10^{35} \; \text{years}[/tex] - Super-Kamiokande

References for the symbolic mathematical proof to this equation and the value of [tex]\alpha_{(5)}[/tex] would be appreciated.
