Proposal for a shared transverse LLP detector for FCC-ee and FCC-hh and a forward LLP detector for FCC-hh
Biplob Bhattacherjee, Camellia Bose, Herbi K. Dreiner +5
As the particle physics community has explored most of the conventional avenues for new physics, the more elusive areas are becoming increasingly appealing. One such potential regi…
A new approach to long-lived particle detection at hadron colliders: the concept
Biplob Bhattacherjee, Arnav Chauhan, Swagata Mukherjee +2
We propose a fundamental shift in the search for beyond the Standard Model long-lived particles (LLPs) at high-luminosity hadron colliders by prioritizing physical background suppr…
Long-lived Light Mediators in a Higgs Portal Model at the FCC-ee
Biplob Bhattacherjee, Camellia Bose, Herbi K. Dreiner +3
In the search for beyond the Standard Model (SM) physics, long-lived particles (LLPs) have emerged as potential candidates and are being explored in various ongoing experiments. Fu…
Current status of the light neutralino thermal dark matter in the phenomenological MSSM
Rahool Kumar Barman, Genevieve Bélanger, Biplob Bhattacherjee +2
In a previous publication, we studied the parameter space of the phenomenological Minimal Supersymmetric Standard Model (pMSSM) with a light neutralino thermal dark matter ($M_{\ti…
From obstacle to opportunity: uncovering the silver lining of pileup
Biplob Bhattacherjee, Abhinav Kumar, Swagata Mukherjee +2
The lack of evidence for Beyond Standard Model (BSM) particles might be due to their light mass and very weak interactions, as exemplified by BSM long-lived particles (LLPs). Such…
Tagging ultra-boosted jets at FCC-hh using machine learning techniques
Sanchari Bhattacharyya, Biplob Bhattacherjee, Camellia Bose +2
The Future Circular Hadron Collider (FCC-hh) will probe unprecedented energy regimes, enabling direct searches for new elementary particles at a scale of tens of TeV. FCC-hh is cur…
