Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

Despite being a well understood phenomenon in the context of current terrestrial
experiments, neutrino flavor conversions in dense astrophysical environments probably …

We analyze the classically scale-invariant BL model in the context of resonant leptogenesis
with the recently proposed mass-gain mechanism. The BL symmetry breaking in this …

We present cosmological results from the measurement of baryon acoustic oscillations
(BAO) in galaxy, quasar and Lyman-$\alpha $ forest tracers from the first year of …

A bstract Based on Quantum Gravity arguments, it has been suggested that all kinetic terms
of light particles below the UV cut-off could arise in the IR via quantum (loop) corrections …

A bstract We propose a tri-hypercharge (TH) extension of the Standard Model (SM) in which
a separate gauged weak hypercharge is associated with each fermion family. In this way …

The observed pattern of lepton flavor mixing and CP violation strongly indicates the possible
existence of a simple flavor symmetry in the neutrino sector—the effective Majorana neutrino …

A bstract We study a scenario where both dark matter and heavy right handed neutrino
(RHN) responsible for leptogenesis acquire masses by crossing the relativistic bubble walls …

A bstract 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 …

A bstract Motivated by searches for so-called leptonic scalars at the LHC and the recent
measurement of the W boson's mass at the Tevatron, we revisit the phenomenology of the …
