Leptonic CP asymmetry and heavy neutrino searches in seesaw scenario
Arindam Das, Wei Liu, Supriya Senapati
We investigate the prospects for probing heavy Majorana neutrinos in the type-I seesaw framework at the 14 TeV LHC. In this scenario, the light-heavy neutrino mixing enables the pr…
Semi-visible emerging jets
Juliana Carrasco, Suchita Kulkarni, Wei Liu +2
We propose a new class of dark-shower signatures in Standard Model extensions featuring Hidden Valleys or dark sectors coupled through an s-channel mediator. In this framework, uns…
Hidden valley scenario sensitivity in the CMS muon endcap detector
Wei Liu, Joshua Lockyer, Suchita Kulkarni
We study the sensitivity of the CMS search to displaced showers arising from the decays of long-lived particles in the muon system, within the framework of Hidden Valley scenarios.…
Probing a left-right symmetric model from a displaced shower at the CMS muon system
Wei Liu, Zixiang Chen
We study the potential collider discovery for the right-handed neutrinos (RHNs) in the minimal left-right symmetric model (LRSM). In this model, the RHNs can be either produced fro…
Revealing the Origin of Neutrino Masses through Displaced Shower Searches in the CMS Muon System
Wei Liu, Suchita Kulkarni, Frank F. Deppisch
We study the potential to probe the origin of neutrino masses, by searching for long-lived right-handed neutrinos (RHNs) in the model and in the RHN-extended Standard Mod…
Testing Leptogenesis and Seesaw using Long-lived Particle Searches in the Model
Wei Liu, Frank F. Deppisch, Zixiang Chen
We discuss the potential of using long-lived particle (LLP) searches for right-handed neutrinos (RHNs) to test resonant leptogenesis and the seesaw mechanism. This is challenging i…
