SUMMARY:Finding the neutrino mass mechanism at muon colliders \, Netwo
 rk in Neutrinos\, Nuclear Astrophysics\, and Symmetries (N3AS) Seminar
 \, Kåre Fridell \, KEK\, Tsukuba
DESCRIPTION:In this talk I will show how neutrino mass mechanisms may 
 be probed in<br>\nfuture muon colliders\, with special emphasis on the
  proposed μTRISTAN<br>\nexperiment. If neutrinos are Majorana particl
 es\, they may lead to<br>\ncharged lepton flavor violating processes t
 hat would constitute clear<br>\nevidence for New Physics in the lepton
  sector. Using an effective field<br>\ntheory framework\, we then comp
 are the potential discovery reach with<br>\nexisting limits from rare 
 lepton decays\, finding that muon colliders are<br>\nthe most sensitiv
 e probe of charged lepton flavor violation for a range<br>\nof paramet
 ers. As a model example\, we then consider the type-ii seesaw<br>\nmod
 el\, and show how a muon collider could be used to constrain the CP-<b
 r>\nviolating phases of the corresponding PMNS matrix.<br>\n
