TLDR
In this paper, it was shown that B − L nonconserving proton decay (p→e − π + π+ etc.) is allowed through gauge boson mixing in both SO(10) and E(6) GUTs.About:

Unification parameter analysis within left-right symmetric SO(10)
F Astorga,W J Stirling +1 more
TL;DR: Within a left-right symmetric model embedded in SO(10), the unification parameters MGUT and 1/ alpha GUT were analyzed as functions of the numbers of fermion families and Higgs multiplets in this paper.

Two-intermediate-scale unification analysis of supersymmetric SO(10) at a two-loop level
TL;DR: It is found that the Higgs contribution is indispensable to attain unification and it also turns out that a two-intermediate-scale scenario allows more freedom in the actual values of these scales constrained by unification.

Grand unified theories and proton decay
Paul Langacker,Paul Langacker +1 more
TL;DR: In this paper, a detailed description of many of the necessary background topics, including gauge theories, spontaneous symmetry breaking, the standard SU2 x U1 electroweak model and its modifications and extensions, Majorana and Dirac neutrino masses, the induced cosmological term, CP violation, quantum chromodynamics and its symmetries, and dynamical symmetry breaking are reviewed.

Operator analysis of new physics
H.A. Weldon,A. Zee +1 more
TL;DR: In this article, the existence of new physics beyond Mw would be signaled by the nonconservation of either the separate lepton numbers Le, Lμ, Lτ, of total lepton number L, or of baryon number B. At low energy these violations are described by an effective theory containing only the known quarks and leptons with vertices of dimension five or higher that are SU(3)×SU(2)×U(1) invariant.

Conservation or Violation of $B^-$l in Proton Decay
Frank Wilczek,A. Zee +1 more
TL;DR: The question of whether or not proton decay conserves baryon minus lepton number is studied in this paper, and it is shown that observation of B − L violation would indicate the existence of physical structure in the mass scale between M W ≃ 10 2 GeV and M X ≈ 10 16 GeV, contrary to the usual supposition about grand unification.
