Constraining the Higgs potential using multi-Higgs production
Jia-Le Ding, Zach Gillis, Ulrich Haisch +10
The Higgs self-couplings remain only weakly constrained by current Large Hadron Collider (LHC) measurements, leaving ample room for physics beyond the Standard Model that could mod…
Two-loop form factors for Dark Matter annihilation to colored Standard Model particles
Warsimakram Katapur, Ambresh Shivaji
We investigate a UV-complete model in which the dark matter (DM) particle interacts with gluons through a colored scalar mediator. This framework provides a phenomenologically viab…
NLO QCD effects on angular observables in in presence of non-standard couplings
Biswajit Das, Pramod Sharma, Ambresh Shivaji
The single Higgs production in neutral-current (NC) and charged-current (CC) processes at an electron-proton () collider is a useful channel to probe new physics effects in the…
Role of angular observables in probing non-standard couplings at an electron-proton collider
Pramod Sharma, Ambresh Shivaji
In this study, we explore various lab-frame angular observables at Large Hadron-electron Collider (LHeC) to test their sensitivity on the most general structure of the Higgs ()…
NLO QCD effects on angular observables in single Higgs production at electron-proton collider
Pramod Sharma, Biswajit Das, Ambresh Shivaji
Properties of the Higgs boson () at current and future particle colliders are crucial to explore new physics beyond the standard model. In particular, experimental and theoretic…
