Electroweak flavour unification

Journal of High Energy Physics, 2022
We propose that the electroweak and flavour quantum numbers of the Standard Model (SM) could be unified at high energies in an SU(4) × Sp(6) L × Sp(6) R anomaly-free gauge model. All the SM fermions are packaged into two fundamental fields, Ψ L ∼ (4 , 6 ,

The Weinberg angle and 5D RGE effects in a SO(11) GUT theory

Physics Letters B, 2020
The Weinberg angle is an important parameter in Grand Unified Theories (GUT) as its size is crucially influenced by the assumption of unification. In scenarios with different steps of symmetry breaking, in particular in models that involve gauge-Higgs ...

Anatomy of scalar mediated proton decays in SO(10) models

Journal of High Energy Physics, 2022
Realistic models based on the renormalizable grand unified theories have varieties of scalars, many of which are capable of mediating baryon (B) and lepton (L) number non-conserving processes.

Predictive power of grand unification from quantum gravity

Journal of High Energy Physics, 2020
If a grand-unified extension of the asymptotically safe Reuter fixed-point for quantum gravity exists, it determines free parameters of the grand-unified scalar potential. All quartic couplings take their fixed-point values in the trans-Planckian regime.

Probing minimal grand unification through gravitational waves, proton decay, and fermion masses

Journal of High Energy Physics, 2023
Motivated by the direct discovery of gravitational waves (GWs) from black holes and neutron stars, there is a growing interest in investigating GWs from other sources.

Partly supersymmetric grand unification [PDF]

Physical Review D, 2005
It is shown how grand unification can occur in models which are partly supersymmetric. The particle states which are composite do not contribute to the running of gauge couplings above the compositeness scale, while the elementary states contribute the usual large logarithmns.

Tri-unification: a separate SU(5) for each fermion family

Journal of High Energy Physics
In this paper we discuss SU(5)3 with cyclic symmetry as a possible grand unified theory (GUT). The basic idea of such a tri-unification is that there is a separate SU(5) for each fermion family, with the light Higgs doublet(s) arising from the third ...

Conditions for suppressing dimension-five proton decay in renormalizable SUSY SO(10) GUT

Journal of High Energy Physics, 2023
The SUSY SO(10) GUT is in severe tension with the experimental bounds on proton partial lifetimes because proton decay mediated by colored Higgsinos (dimension-five proton decay) is too rapid.

Implications of a dark grand unification

Journal of High Energy Physics
Given that dark matter and normal matter are nontrivially unified in a grand unified theory, called dark grand unification, we derive novel residual theories at low energy explaining dark matter and neutrino mass.

Asymptotic grand unification in SO(10) with one extra dimension

Journal of High Energy Physics
Asymptotic grand unification provides an alternative approach to gradually unify gauge couplings in the UV limit, where they reach a non-trivial UV fixed point.
