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…

Electroweak phase transition in SMEFT: Gravitational wave and collider complementarity

Sahabub Jahedi, Indrajit Saha, Abhik Sarkar

We study the first-order electroweak phase transition (FO-EWPT) within the Standard Model Effective Field Theory (SMEFT) framework induced by dimension-6 operators. Such phenomena…

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…

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…
