High energy probes of Higgs self-coupling via boson fusion at future lepton colliders
Amir Subba, Hrishikesh Deka, Subhaditya Bhattacharya +1
We investigate the sensitivity to the Higgs self-coupling through boson fusion di-Higgs production at CLIC with a center-of-mass energy of TeV. We study the interp…
Probing ALP-portal fermionic dark matter at the colliders
Subhaditya Bhattacharya, Sahabub Jahedi, Soumen Kumar Manna +1
Axion-like particles (ALPs) are promising candidates for mediating interactions between a dark sector and the Standard Model (SM). In this work, considering the effective interacti…
Probing lepton number violating SMEFT operators at the same-sign muon collider
Subhaditya Bhattacharya, Soumyajit Datta, Abhik Sarkar
We investigate lepton number violation (LNV) induced by dimension-seven Standard Model Effective Field Theory (SMEFT) operators in the context of same-sign muon colliders…
Probing CP-violating Higgs-Gauge couplings with Higgsstrahlung at collider
Amir Subba, Subhaditya Bhattacharya, Abhik Sarkar
We investigate the sensitivity of a future high-luminosity collider operating at to CP-violating and CP-conserving anomalous interactions v…
Exploring Leptogenesis, WIMP Dark Matter, and Gravitational Waves in an extended Scalar Framework
Subhaditya Bhattacharya, Niloy Mondal, Arunansu Sil
We explore extensions of type I seesaw framework with a scalar mediator () connecting to a complex scalar dark field (), and right handed neutrinos (), with an aim to c…
Optimal estimation of Higgs-Gauge Boson couplings at the future colliders
Subhaditya Bhattacharya, Amir Subba, Abhik Sarkar
The proposed collider offers an ideal environment for precise estimation of Higgs boson properties which are of utmost importance to validate the Standard Model of particl…
