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…

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…

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…
