Axion-like particles from soft supersymmetry breaking
Gayatri Ghosh
We study a supersymmetric effective field theory in which the mass of an axion-like particle (ALP) is generated predominantly by soft supersymmetry-breaking effects. The Peccei--Qu…
The Weak Gravity Conjecture in Asymptotically Safe Quantum Gravity
Gayatri Ghosh
The Weak Gravity Conjecture (WGC) posits that gravity must be the weakest force in any consistent theory of quantum gravity. Originally formulated to constrain the landscape of eff…
CP Violation and Flavour-Violating Di-Higgs Couplings in the Randall-Sundrum Model
Gayatri Ghosh
The Randall-Sundrum (RS) model offers a compelling framework to address the hierarchy problem and provides new sources of CP violation beyond the Standard Model (SM). The motivatio…
Annihilation of NMSSM neutralinos and Branching Ratios, Particle Decay Channel of lightest CP odd, even Higgs in NMSSM
Gayatri Ghosh
The nexttominimal supersymmetric standard model (NMSSM) featuring constrained mSUGRA model, has the capability to inherently anticipate a light dark matter component within t…
