Exact Lattice Identities and Continuum-Limit Dyson--Schwinger Equations for Yang-Mills Theory
Arpan Chatterjee, Marco Frasca, Anish Ghoshal +1
Starting from SU(N) on the lattice, we give a rigorous derivation of the Dyson--Schwinger equations in the continuum limit. We formulate the Dyson--Schwinger identities for the lat…
Magnetically assisted primordial scalar perturbations: Scalar-Induced Gravitational Waves
Arko Bhaumik, Theodoros Papanikolaou, Anish Ghoshal
Primordial magnetic fields (PMFs) provide a well-motivated source of cosmological perturbations through their anisotropic stress and may leave observable imprints in both the scala…
Particle production from bubble collisions
Anish Ghoshal, Pratyay Pal, Alessandro Strumia
The paper investigates how ultra‑relativistic bubble collisions during cosmological phase transitions can generate very heavy particles, introducing a partonic‑like formalism based…
Quintessence Dark Energy from non-perturbative Higgs-Yang-Mills mass gap
Marco Frasca, Anish Ghoshal, Massimiliano Rinaldi
We discuss the equations that arise from a Higgs--Yang-Mills dark sector coupled to gravity on a flat Friedmann-Lemaitre-Robinson-Walker metric. We choose the simplest repr…
Irreducible Gravitational Wave Background as a Particle Detector
Anish Ghoshal, Angus Spalding, Graham White
We show that spectral features of primordial gravitational-wave backgrounds (GWB) can directly reconstruct \textit{Lagrangian} parameters of beyond-the-Standard-Model (BSM) particl…
Cosmic Strings Gravitational Wave Probe of Leptogenesis: Thermal, Non-thermal, Near-resonant and Flavourful
Anish Ghoshal, Angus Spalding, Graham White
Breaking a global or local symmetry at high scales simultaneously generates Majorana masses for heavy right-handed neutrinos and produces a network of cosmic strin…
