The search of heavy Majorana neutrino is a long-standing topic in the field of high-energy physics and BSM physics. High-energy muon colliders are potentially ideal machines in both energy and precision frontiers. We proposed a clear lepton-number-violating signature through vector boson scattering to search for heavy Majorana neutrino at both 𝜇^+ 𝜇^− and 𝜇^+ 𝜇^+ colliders (JHEP 09 (2023) 131,...
Heavy neutral gauge boson $Z^\prime$ is proposed in many new physics models. It has rich phenomena at the future muon collider. We study the properties of $Z^\prime$ boson with the process of $\mu^+ \mu^- \rightarrow q \bar{q}$, $\mu^+ \mu^- \rightarrow l^+ l^-$, $\mu^+ \mu^- \rightarrow Z H$ and $\mu^+ \mu^- \rightarrow W^+ W^-$.
$\Delta L = 2 $ lepton number violation at the TeV scale connects $0\nu\beta\beta$ decay (intensity frontier), LHC searches (energy frontier), and leptogenesis (cosmic frontier). I will focus on some progress on the promising UV completions of $0\nu\beta\beta$ decay operators, which can be diagnosed with complementary searches at the HL-LHC and HE-LHC.
