Shedding Flavor on Dark via Freeze-in: Gauged Extensions
Basabendu Barman, Purusottam Ghosh, Anish Ghoshal +1
We consider a singlet fermionic dark matter (DM) in a gauged extension of the Standard Model (SM), with , and derive bounds on the allowed param…
Gravitational Wave Gastronomy
David I. Dunsky, Anish Ghoshal, Hitoshi Murayama +2
The symmetry breaking of grand unified gauge groups in the early Universe often leaves behind relic topological defects such as cosmic strings, domain walls, or monopoles. For some…
Nambu-Jona-Lasinio model correlation functions from QCD
Marco Frasca, Anish Ghoshal, Stefan Groote
We treat quantum chromodynamics (QCD) using a set of Dyson-Schwinger equations derived, in differential form, with the Bender-Milton-Savage technique. In this way, we are able to d…
On a novel evalutation of the hadronic contribution to the muon's from QCD
Marco Frasca, Anish Ghoshal, Stefan Groote
We evaluate the hadronic contribution to the of the muon by deriving the low-energy limit of quantum chromodynamics (QCD) and computing in this way the hadronic vacuum polari…
Scale Invariant FIMP Miracle
Basabendu Barman, Anish Ghoshal
We study the freeze-in production of vector dark matter (DM) in a classically scale invariant theory, where the Standard Model (SM) is augmented with an abelian gauge symm…
Confinement and Renormalization Group Equations in String-inspired Non-local Gauge Theories
Marco Frasca, Anish Ghoshal, Nobuchika Okada
As an extension of the weak perturbation theory obtained in recent analysis on infinite-derivative non-local non-Abelian gauge theories motivated from p-adic string field theory, a…
Constraints on Tsallis Cosmology from Big Bang Nucleosynthesis and Dark Matter Freeze-out
Anish Ghoshal, Gaetano Lambiase
We consider Tsallis cosmology as an approach to thermodynamic gravity and derive the bound on the Tsallis parameter to be by using the constraints derived from the formation…
Shedding Light on Dark Matter and Neutrino Interactions from Cosmology
Arnab Paul, Arindam Chatterjee, Anish Ghoshal +1
In CDM cosmology, Dark Matter (DM) and neutrinos are assumed to be non-interacting. However, it is possible to have scenarios, where DM-neutrino interaction may be present, l…
Strongly Coupled String-inspired Infinite Derivative Non-local Yang-Mills: Diluted Mass Gap
Marco Frasca, Anish Ghoshal
We investigate the non-perturbative regimes in the class of non-Abelian theories that have been proposed as an ultraviolet completion 4-D Quantum Field Theory (QFT) generalizing th…
