An EFT study of the process at the FCC-
Shankha Banerjee, Rick S. Gupta, Shilpi Jain +2
We carry out an Effective Field Theory (EFT) study of the process in the $4b + 3 \ell + \ge 2j + \slashed{E}_T$ final state. This process can uniquely probe t…

We study the prospects for observing exotic decays of the Standard Model Higgs boson into light beyond the Standard Model scalars with mass in the…
Effective limits on single scalar extensions in the light of recent LHC data
Anisha, Supratim Das Bakshi, Shankha Banerjee +4
In this paper, we work with 16 different single scalar particle extensions of the Standard Model. We present the sets of dimension-6 effective operators and the associated Wilson c…
Phenomenological analysis of multi-pseudoscalar mediated dark matter models
Shankha Banerjee, Geneviève Bélanger, Disha Bhatia +2
Non-minimal simplified extensions of the Standard Model have gained considerable currency in the context of dark matter searches at the LHC, since they predict enhanced mono-Higgs…
Unveiling Hidden Physics at the LHC
Oliver Fischer, Bruce Mellado, Stefan Antusch +30
The field of particle physics is at the crossroads. The discovery of a Higgs-like boson completed the Standard Model (SM), but the lacking observation of convincing resonances Beyo…

Shankha Banerjee, Rick S. Gupta, Oscar Ochoa-Valeriano +1
We study standard electroweak/Higgs processes at the high-energy lepton colliders ILC and CLIC. We identify a subset of three operators in the SMEFT that give leading contributions…

Shankha Banerjee, Fawzi Boudjema, Nabarun Chakrabarty +1
One-loop electroweak corrections to the annihilation cross-sections of dark matter in the Higgs resonance region of the inert doublet model (IDM) are investigated. The procedure of…

Shankha Banerjee, Fawzi Boudjema, Nabarun Chakrabarty +1
We perform the first one-loop electroweak corrections for processes for dark matter annihilation. These are the dominant processes that enter the computation of the relic…
Relic density of dark matter in the inert doublet model beyond leading order for the low mass region: 2. Co-annihilation
Shankha Banerjee, Fawzi Boudjema, Nabarun Chakrabarty +1
We examine the relic density of the light mass dark matter region in the inert doublet model (IDM) when the dominant process is due to co-annihilation between the lightest neutral…

The present paper is the first in a series that addresses the calculation of the full one-loop corrections of dark matter (DM) annihilation cross-sections in the low mass region of…
A fully differential SMEFT analysis of the golden channel using the method of moments
Shankha Banerjee, Rick S. Gupta, Oscar Ochoa-Valeriano +2
The Method of Moments is a powerful framework to disentangle the relative contributions of amplitudes of a specific process to its various phase space regions. We apply this method…
