Renormalization group running of neutrino parameters

, 2014
Neutrinos are the most elusive particles in our universe. They have masses at least one million times smaller than the electron mass, carry no electric charge, and very weakly interact with other particles, meaning they are rarely captured in terrestrial

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 ...

Radiative mass mechanism: addressing the flavour hierarchy and strong CP puzzle

Journal of High Energy Physics
We propose a class of models based on the parity invariant Left-Right Symmetric Model (LRSM), which incorporates the mechanism of radiative generation of fermion masses while simultaneously possessing the solution to the Strong CP problem.

The gauge coupling evolutions of an SU(8) theory with the maximally symmetry breaking pattern

Journal of High Energy Physics
We study the renormalizable group equations (RGEs) of the extended strong and weak gauge couplings in an SU(8) theory, where three-generational SM fermions are non-trivially embedded.

A Theory of Flavour and Set of the Interaction Structural Parts

, 2007
At the availability of a sharp interconnection, the difference in sizes with Dirac and Pauli form factors of a massive neutrino must constitute their linearly ordered set. Such a class of currents can lead in the field of a spinless nucleus to the constitution of a partially ordered set consisting of cross sections of polarized and unpolarized neutrino

The flavouring of the pomeron and reggeon field theory with thresholds

Physics Letters B, 1978
Abstract The flavoured pomeron is introduced into reggeon field theory to show that, in the absence of a secondary vacuum trajectory P′, the critical solution is in fair agreement with experimental data.

A modular SU (5) littlest seesaw

Journal of High Energy Physics
We extend the littlest modular seesaw to a Grand Unified scenario based on SU (5) endowed with three modular S 4 symmetries. We leverage symmetry protected zeroes in the leptonic and down quark sectors to suppress deviations to the littlest modular ...

A roadmap for neutrino charge assignments in U(2) F flavor models: implications for LFV processes and leptonic anomalous magnetic moments

Journal of High Energy Physics
We build upon a simple U(2) F model of flavor, in which all fermion masses and mixing hierarchies arise from powers of two small parameters controlling U(2) F breaking. In the original formulation, an isomorphism to the discrete D 6 × U(1) F symmetry was
