Revised exclusion limits on doubly charged Higgs bosons from a reanalysis of the ATLAS multi-lepton search at ,TeV
Kirtiman Ghosh, Arun Kumar Nayak, Debabrata Sahoo
The ATLAS search for pair-produced doubly charged Higgs bosons in multi-lepton final states using the full Run 2 dataset [Eur. Phys. J. C 83 (2023) 605] reports the strongest limit…
Resurrecting Kaluza-Klein Dark Matter with Low-Temperature Reheating
Kirtiman Ghosh, Abhishek Roy, Rameswar Sahu
In Universal Extra Dimension (UED) scenarios, the lightest Kaluza-Klein (KK) particle is naturally stable due to a remnant discrete symmetry, KK parity, arising from extra-dimensio…
Reinterpretation and preservation of data and analyses in HEP
Jon Butterworth, Sabine Kraml, Harrison Prosper +145
Data from particle physics experiments are unique and are often the result of a very large investment of resources. Given the potential scientific impact of these data, which goes…
Multipartite dark matter in a gauge theory of leptons
Utkarsh Patel, Avnish, Sudhanwa Patra +1
The classical conservation of the lepton number is an accidental symmetry present in the Standard Model (SM). Thus, we consider here a scenario where the SM is extended with a U(1)…
A Comprehensive Search for Leptoquarks Decaying into Top- Final States at the Future LHC
Debabrata Sahoo, Rameswar Sahu, Kirtiman Ghosh
We studied the collider phenomenology of third-generation scalar leptoquarks at the Large Hadron Collider (LHC) with a 14 TeV center-of-mass energy. The analysis focuses on leptoqu…
Advancing Higgsino Searches by Integrating ML for Boosted Object Tagging and Event Selection
Rameswar Sahu, Debabrata Sahoo, Kirtiman Ghosh
Higgsinos near the TeV mass range are highly motivated as they offer an elegant solution to the naturalness problem in the Standard Model. Extensive searches for such higgsinos wit…
