A bstract We investigate for viable models of inflation that can successfully produce dark
matter (DM) from inflaton decay process, satisfying all the constraints from Cosmic …

We show that a baryon asymmetry can be generated by dissipative effects during warm
inflation via a supersymmetric two-stage mechanism, where the inflaton is coupled to heavy …

We study the possibility that primordial black holes (PBHs) can be formed from large
curvature perturbations generated during the waterfall phase transition due to the effects of …

A bstract In this work we show that modifying the thermal history of the Universe by including
an early period of matter domination can lead to the formation of astronomical objects …

We revisit the small-field Coleman-Weinberg inflation, which has the following two problems:
First, the smallness of the slow roll parameter ε requires the inflation scale to be very low …

Abstract f (R) f (R)-theories of gravity are reviewed in the framework of the matter-antimatter
asymmetry in the Universe. The asymmetry is generated by the gravitational coupling of …

In this work, we have explored the possibilities of improving CP violation (CPV) discovery
potential of newly planned Long-Baseline Neutrino Experiment (LBNE), USA, by combining …

With this thesis the author contributes to the development of a non-mainstream but long-
standing approach to electroweak symmetry breaking based on an analogy with …

We present a realization of the idea that the Higgs boson is mainly a bound state of
neutrinos induced by strong four-fermion interactions. The conflicts of this idea with the …

A bstract Our motivation is to study a dynamics which has the ambition to underlie models of
the electroweak symmetry breaking via the condensation of known fermions. The right …
