Neutrino mixing in a grand unified theory [PDF]

open access: yes, 1980
Neutrino mixing in a grand unified theory in which the neutrino mass matrix is determined by the Gell-Mann-Ramond-Slansky mechanism was investigated. With an arbitrary real right-handed Majorana mass matrix which incorporates three neutrino mass scales ...

331 models and grand unification: From minimal SU(5) to minimal SU(6)

open access: yesPhysics Letters B, 2016
We consider the possibility of grand unification of the SU(3)c⊗SU(3)L⊗U(1)X model in an SU(6) gauge unification group. Two possibilities arise. Unlike other conventional grand unified theories, in SU(6) one can embed the 331 model as a subgroup such that

GUT and Flavor Models for Neutrino Masses and Mixing

open access: yesFrontiers in Physics, 2017
In the recent years neutrino experiments have studied in detail the phenomenon of neutrino oscillations and most of the oscillation parameters have been measured with a good accuracy.

THEORETICAL FRAMEWORKS FOR UNIFIED FIELD THEORY: PROGRESS AND CHALLENGES

open access: yesWorldwide Journal of Physics, 2023
The quest for a Unified Field Theory (UFT) represents a cornerstone challenge in theoretical physics, aiming to integrate all fundamental interactions—gravitational, electromagnetic, weak, and strong forces—into a singular, coherent framework. This study

Phases of confining SU(5) chiral gauge theory with three generations

open access: yesJournal of High Energy Physics, 2022
We explore the possible low energy phases of the confining non-supersymmetric SU(5) chiral gauge theory with three generations of fermions in the (10+ 5 ¯ $$ \overline{5} $$ ) representations.

Probing grand unification with quantum sensors

open access: yesPhysics Letters B
We discuss how grand unification can be probed with experiments at low energies using quantum sensors. Specifically, we show that scalar multiplets coupled to the gauge sector of a grand unified theory provide a mechanism for a time-varying unified ...

Gravitational Breaking of the Grand Unified Theory Group and the Grand Unified Theory–Planck Hierarchy [PDF]

open access: yesPhysical Review Letters, 1996
It is shown that nonrenormalizable gravitational interactions in the Higgs sector of supersymmetric grand unified theories (GUTs) can produce the breaking of the unifying gauge group {ital G} at the GUT scale {ital M}{sub GUT}{approximately}10{sup 16} GeV.

Axion couplings in grand unified theories

open access: yesJournal of High Energy Physics, 2022
Abstract We show that the couplings of axions to gauge bosons are highly restricted in Grand Unified Theories where the standard model is embedded in a simple 4D gauge group. The topological nature of these couplings allows them to be matched from the UV to the IR, and the ratio of the anomaly with photons and gluons for any axion ...

Unification of the standard model and dark matter sectors in [SU(5) × U(1)]4

open access: yesJournal of High Energy Physics, 2019
A simple model of dark matter contains a light Dirac field charged under a hidden U(1) gauge symmetry. When a chiral matter content in a strong dynamics satisfies the t’Hooft anomaly matching condition, a massless baryon is a natural candidate of the ...
