However, due to its particle content, the model preserves a global symmetry, where B and L are baryon and lepton numbers, respectively. It thus leaves neutrinos massless just as the Standard Model does. The extensions of the Georgi-Glashow model that break lepton number by two units, i.e., scenarios with operator(s), naturally generate potentially viable Majorana neutrino masses. Since the dynamics that yields interactions unavoidably induces transitions via breaking, these extensions consequentially lead to intriguing processes such as neutron–antineutron (n– ) oscillation. We investigate this intrinsic connection between neutrino mass generation and n– oscillation within a number of representative extensions of the Georgi-Glashow model that can yield realistic neutrino masses and mixing parameters. These extensions include the tree-level seesaw mechanism realizations of the Type I, II, and III varieties, as well as the one-loop and two-loop radiative neutrino mass models.Elsevier20262026-06-23 12:02:16Neznano30359Nizozemskasl© 2026 The Author(s).
