Status of light inflaton: from inflation to laboratory
Niloy Mondal, Shashwat Sharma, Mathew Thomas Arun +1
We investigate the viability of the light inflaton scenario in light of the latest inflationary constraints from the Atacama Cosmology Telescope (ACT), together with bounds from co…
Learning holographic QCD with unflavored meson spectra
Mathew Thomas Arun, Ritik Pal
We develop a data-driven neural network framework to reconstruct the five-dimensional background geometry, the dilaton potential, and the chiral-symmetry-breaking scalar potential…
From WIMP to FIMP during reheating: collider vs non-collider probes for p-wave annihilation
Dipankar Pradhan, Niloy Mondal, Abhik Sarkar +4
By examining the transition from freeze-out to freeze-in dark matter (DM) production within the framework of perturbative reheating, where DM interacts with the visible sector thro…
RG evolution and effect of intermediate new-physics on four-fermion operators
Mathew Thomas Arun, Shyam M, Ritik Pal
Motivated by the stringent experimental bounds on proton lifetime and the need for precise low-energy predictions, there has been renewed interest in the renormalization group (RG)…
RG evolution and effect of intermediate new physics on six-quark operators
Mathew Thomas Arun, Shyam M, Ritik Pal
The recent identification of possible 11 neutron-antineutron (-) oscillation candidate events at Super-Kamiokande has renewed the interest in transitions. In…
On the role of cosmological constant in modeling hadrons
Mathew Thomas Arun, Nabeel Thahir
Einsteins gravity with a cosmological constant in four dimensions can be reformulated as a theory characterized solely by the dimensionless coupling $λ\propto G_N ΅
