Heavy neutral leptons from light scalar in fixed target and forward search experiments
ShivaSankar K. A., Souvik Das, Arindam Das +1
The observation of neutrino masses strongly motivates extensions of the Standard Model, in which heavy neutral leptons acquire Majorana masses through spontaneous $U(1…
Quantum spin correlations in -mediated production at future lepton colliders
ShivaSankar K. A., Arindam Das, Sanjoy Mandal
The paper examines how quantum spin correlations in top‑quark pair production at future lepton colliders can reveal the presence of a neutral Z′ gauge boson from anomaly‑free U(1)…
Forward Searches for Heavy Neutrinos and Bosons at FCC-hh
ShivaSankar K. A., Souvik Das, Arindam Das +1
The discovery of neutrino masses strongly motivates extensions of the Standard Model containing heavy neutral leptons and additional gauge interactions. We investigate the prospect…
Right handed neutrino production from interactions in forward search experiments
ShivaSankar K. A, Souvik Das, Arindam Das +1
We study two general extensions of the Standard Model (SM) those generate tiny neutrino masses via the seesaw mechanism after general breaking. These models predict a…
Lepton number violation from Higgs/ decays into a pair of right-handed neutrinos
Arindam Das, Takaaki Nomura, Kei Yagyu
We explore signatures of Lepton Number Violation (LNV) from decays of the discovered Higgs () and Z bosons into a pair of Right-Handed Neutrinos (RHNs). Due to the Majorana natu…
New Physics Search at the CEPC: a General Perspective
Xiaocong Ai, Stefan Antusch, Peter Athron +211
The Circular Electron-Positron Collider (CEPC), a proposed next-generation Higgs factory, provides new opportunities to explore physics beyond the Standard Model (SM). With its cle…
