Grand Unification Higgs- Inflation: Complementarity between Proton Decay and CMB Observables
Nilay Bostan, Rafid H. Dejrah, Anish Ghoshal
We propose a predictive Grand Unified Theory (GUT) framework for cosmic inflation in the Palatini formulation of gravity. In this model, a GUT Higgs field…
Large Field Polynomial Inflation in Palatini Gravity
Nilay Bostan, Canan Karahan, Ozan Sargın
In this paper, we employ the Palatini formalism to investigate the dynamics of large-field inflation using a renormalizable polynomial inflaton potential in the context of …
Minimally coupled -exponential inflation with an term in the Palatini formulation
Nilay Bostan, Rafid H. Dejrah
We focus on the inflationary predictions of -exponential potential models, in which the inflaton is a representation of the field delineating the size of extra-dimension. Since…
First constraints on non-minimally coupled Natural and Coleman-Weinberg inflation and massive neutrino self-interactions with Planck+BICEP/Keck
Nilay Bostan, Shouvik Roy Choudhury
In this work, for the first time in literature, we study the predictions of non-minimally coupled Natural and Coleman-Weinberg potentials in the plane, and an extended C…
Inflation in Symmergent Metric-Palatini Gravity
Nilay Bostan, Canan Karahan, Ozan Sargın
In this paper, we study the cosmological inflation phenomenon in symmergent gravity theory. Symmergent gravity is a novel framework which merges gravity and the standard model (SM)…
Non-minimally coupled Natural Inflation: Palatini and Metric formalism with the recent BICEP/Keck
Nilay Bostan
In this work, we show the effect of the non-minimal coupling on the inflationary parameters by considering the single-field inflation and present the inflationary predicti…
Preheating in radiative corrections to inflation with non-minimal coupling in Palatini formulation
Nilay Bostan
We discuss the impact of the preheating stage in radiative corrections due to interaction of the inflaton to fermions to inflation with non-minimal coupling in Palatini formu…
Quadratic, Higgs and hilltop potentials in the Palatini gravity
Nilay Bostan
In this work, we study inflation with the non-minimally coupled quadratic, Standard Model (SM) Higgs and hilltop potentials through term in the Palatini gravity. We first a…
Quartic inflation and radiative corrections with non-minimal coupling
Nilay Bostan, Vedat Nefer Şenoğuz
It is well known that the non-minimal coupling between the inflaton and the Ricci scalar affects predictions of single field inflation models. In particular, the qua…
