Probing Lepton Number Violation and Majorana Nature of Neutrinos at the LHC
K. S. Babu, Rahool Kumar Barman, Dorival Gonçalves +1
Observation of lepton number () violation by two units at colliders would provide evidence for the Majorana nature of neutrinos. We study signals of -violation in the context…
Prospects for exotic decays in single and di-Higgs boson production at the LHC and future hadron colliders
Amit Adhikary, Shankha Banerjee, Rahool Kumar Barman +5
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…
Constraining Lepton Flavor Violating Higgs Couplings at the HL-LHC in the Vector Boson Fusion Channel
Rahool Kumar Barman, P. S. Bhupal Dev, Anil Thapa
We explore the parameter space of lepton flavor violating (LFV) neutral Higgs Yukawa couplings with the muon and tau leptons that can be probed at the high-luminosity Large Hadron…
Report of the Topical Group on Higgs Physics for Snowmass 2021: The Case for Precision Higgs Physics
Sally Dawson, Patrick Meade, Isobel Ojalvo +78
A future Higgs Factory will provide improved precision on measurements of Higgs couplings beyond those obtained by the LHC, and will enable a broad range of investigations across t…
Long live The NMSSM!
Amit Adhikary, Rahool Kumar Barman, Biplob Bhattacherjee +3
We analyze the scenario within the Next to Minimal Supersymmetric Standard Model (NMSSM), where the lightest supersymmetric particle (LSP) is singlino-like neutralino. By systemati…
Is the light neutralino thermal dark matter in the pMSSM ruled out?
Rahool Kumar Barman, Geneviève Bélanger, Biplob Bhattacherjee +2
We explore the parameter space of the phenomenological Minimal Supersymmetric Standard Model (pMSSM) with a light neutralino thermal dark matter () that…
Constraining the top electroweak sector of the SMEFT through associated top pair and single top production at the HL-LHC
Rahool Kumar Barman, Ahmed Ismail
We study the processes and in the framework of Standard Model Effective Field Theory (SMEFT), employing conventional cut-and-count as well as machin…
Snowmass White Paper: Prospects of CP-violation measurements with the Higgs boson at future experiments
A. V. Gritsan, H. Bahl, R. K. Barman +15
The search for CP violation in interactions of the Higgs boson with either fermions or bosons provides attractive reference measurements in the Particle Physics Community Planning…
Directly Probing the CP-structure of the Higgs-Top Yukawa at HL-LHC and Future Colliders
Rahool Kumar Barman, Morgan E. Cassidy, Zhongtian Dong +8
Constraining the Higgs boson properties is a cornerstone of the LHC program and future colliders. In this Snowmass contribution, we study the potential to directly probe the Higgs-…
Machine Learning and LHC Event Generation
Anja Butter, Tilman Plehn, Steffen Schumann +48
First-principle simulations are at the heart of the high-energy physics research program. They link the vast data output of multi-purpose detectors with fundamental theory predicti…
