| May 12, 2020 at 0:54 | comment | added | SAMCRO | I fixed the alpha's G. Smith. So the lifetime of the proton (assuming a 100%) branching ratio i.e. proton decays to a neutral pion and muon all the time, is limited to be >7.7 10^{33} years. From this calculation you can tune the mass of the gauge boson associated to the GUT (M_X) to be sufficiently heavy such that this constraint can be easily satisfied. So the lifetime depends on the mass of this M_X. Also on the mixing maxing entries of U (PMNS matrix). | |

| May 11, 2020 at 21:53 | comment | added | G. Smith | This looks correct now. Three final tiny quibbles: There is no reason to put brackets around “GeV”, just like you don’t put them around “years”. You wrote $\alpha_S$ instead of $\alpha_5$. You have some intermediate values with an unjustified number of significant digits. But all the serious problems have been fixed. | |
