We investigate correlation between gauge coupling unification, fermion mass spectrum, proton decay, perturbativity and ultraviolet cutoff within an SU(5) grand unified theory with minimal scalar content and an extra adjoint representation of fermions. We find strong correlation between the upper bound on the mass of both the bosonic and fermionic SU(2) triplets and the cutoff. The upper bound on the mass of fermionic triplet responsible for Type III seesaw mechanism is 102.1 GeV for the Planck…

Probing Seesaw in an Adjoint SUSY SU(5) Model at LHC

• Physics
• 2010
The SU(5) GUT model extended with fermions in the adjoint 24F representation predicts triplet fermions in the 100 GeV mass range, opening up the possibility of testing seesaw at LHC. However, once

Neutrino Mass, Coupling Unification, Verifiable Proton Decay, Vacuum Stability, and WIMP Dark Matter in SU(5)

• Physics
• 2018
Nonsupersymmetric minimal SU(5) with Higgs representations 24H and 5H and standard fermions in 5¯F⊕10F is well known for its failure in unification of gauge couplings and lack of predicting neutrino

Two Higgs doublet type III seesaw with μ-τ symmetry at LHC

• Physics
• 2009
We propose a two Higgs doublet Type III seesaw model with μ-τ flavor symmetry. We add an additional SU(2) Higgs doublet and three SU(2) fermion triplets in our model. The presence of two Higgs

A colored weak singlet scalar state with hypercharge 4/3 is one of the possible candidates for the explanation of the unexpectedly large forward-backward asymmetry in $t\bar{t}$ production as

Renormalizable SU(5) Unification

• Physics

We propose a simple renormalizable grand unified theory based on the SU(5) gauge symmetry where the neutrino masses are generated at the quantum level through the Zee mechanism. In this model the

Seesaw at LHC

We study the implementation of the type III seesaw in the ordinary nonsupersymmetric SU(5) grand unified theory. This allows for an alternative definition of the minimal SU(5) model, with the

Neutrino Masses and Mixings in Gauge Models with Spontaneous Parity Violation

Unified electroweak gauge theories based on the gauge group SU(2)/sub L/ x SU(2)/sub R/ x U(1)/sub B/-L, in which the breakdown of parity invariance is spontaneous, lead most naturally to a massive

Upper bound on the proton lifetime and the minimal non-SUSY grand unified theory

In this talk I show that it is possible to find an upper bound on the total proton lifetime. I conclude that the simplest realistic non‐supersymmetric grand unified theory is based on SU(5) with a

Minimal Realistic SU(5) Scenario

We present phenomenological aspects of the simplest realistic SU(5) grand unified theory--the theory with the 5, 15, and 24 dimensional representations in the Higgs sector. We show that a successful
