Heavy Neutral Leptons at Muon Colliders
abstract
The future high-energy muon colliders, featuring both high energy and low background, could play a critical role in our searches for new physics. The smallness of neutrino mass is a puzzle of particle physics. Broad classes of solutions to the neutrino puzzles can be best tested by seeking the partners of SM light neutrinos, dubbed as heavy neutral leptons (HNLs), at muon colliders. We can parametrize HNLs in terms of the mass $m_N$ and the mixing angle with $\ell$-flavor $U_\ell$. In this work, we focus on the regime $m_N > O(100)$ GeV and study the projected sensitivities on the $|U_\ell|^2 - m_N$ plane with the full-reconstructable HNL decay into a hadronic $W$ and a charged lepton. The projected reach in $|U_\ell|^2$ leads to the best sensitivities in the TeV realm.

Revealing Neutrino Mass Ordering at CEPC and FCC-ee
In the minimal two-HNL seesaw, heavy neutral lepton flavor mixings encode the normal vs inverted neutrino mass ordering, and CEPC/FCC-ee could distinguish them for total mixing U_tot^2 ≳ 10^-6.

Search for heavy Majorana neutrinos at muon-proton colliders via lepton-number-violating signals
Simulates LNV signals from heavy Majorana neutrinos (200-3000 GeV) at a 5.3 TeV μp collider and projects 2σ limits on |V_ℓN|² superior to LHC bounds for 100 fb⁻¹ and 1 ab⁻¹ luminosities.

New Avenues of Heavy Neutral Lepton at Muon Collider
In a U(1) gauged seesaw model, Z'Z' fusion processes at muon colliders enable HNL pair production via Z'Z'→H→NN and Z'Z'→NN, yielding LNV signals not suppressed by Higgs mixing.

Exotic Higgs Decays at a Muon Collider
Muon colliders at 3 TeV and 10 TeV can probe branching ratios for h to SS decays in 4b and 2b2μ channels down to 10^{-3}–10^{-5}, improving on HL-LHC projections using machine learning.

Non-Standard Neutrino Interactions at Neutrino Experiments and Colliders
Collider searches are generally more constraining than neutrino measurements on simplified models of non-standard neutrino interactions, except possibly for muon-philic leptoquarks and certain heavy neutral leptons.
