Proton decay - Experimental evidence: Encyclopedia II - Proton decay - Theoretical motivation

Despite the lack of observational evidence for proton decay, some grand unification theories require it. According to some such theories, the proton would have a half-life of 1036 years, and would decay into a positron and a pion that itself immediately decays into photons in the range of gamma radiation. p → e+π0 Though this process has not been observed experimentally, it is within the realm of experimental testability for future planned very larg ...

Proton decay - Experimental evidence: Encyclopedia II - Proton decay - Dimension-4 proton decay operators

In the absence of matter parity, supersymmetric extensions of the Standard Model can give rise to the last operator suppressed by the inverse square of sdown quark mass. This is due to the dimension-4 operators and The proton decay rate is only suppressed by which is far too fast. ...

Proton decay - Experimental evidence: Encyclopedia II - Proton decay - Dimension-6 proton decay operators

They are , , and where Λ is the cutoff scale for the Standard Model. All of these operators violate both baryon number and lepton number but not the combination B−L. In GUT models, the exchange of an X or Y boson with the mass ΛGUT can lead to the last two operators suppressed by . The exchange of a triplet Higgs with mass M can lead to all of the operators suppressed by 1/ ...
