DESCRIPTION:Speakers: Ming-Wei Li (Tsung-Dao Lee Institute)\n\n \nNeutrin
 o oscillation experiments have established that neutrinos have nonzero mas
 ses and lepton flavor mixing. This is currently the only firmly establishe
 d experimental evidence in particle physics for physics beyond the Standar
 d Model. It motivates several fundamental questions: whether neutrinos are
  Majorana particles\, how their tiny masses are generated\, and whether ne
 utrino non-standard interactions exist. Among Standard Model fermions\, on
 ly neutrinos can potentially be their own antiparticles. Their Majorana na
 ture is closely connected to lepton number violation\, CP violation\, and 
 possible clues to the matter-antimatter asymmetry of the Universe. On the 
 other hand\, generating neutrino masses usually requires new particles bey
 ond the Standard Model. For example\, in the type-II seesaw mechanism\, an
  electroweak scalar triplet Higgs field generates Majorana neutrino masses
 \, while the introduction of new particles can also lead to non-standard i
 nteractions. This talk will focus on the Majorana nature of neutrinos and 
 non-standard interactions\, using the type-II seesaw mechanism and a Z' mo
 del as two illustrative examples.\n \nBio:\n Ming-Wei Li received his Ph.
 D. from the Tsung-Dao Lee Institute\, Shanghai Jiao Tong University\, and 
 his bachelor’s degree from Cuiying Honors College\, Lanzhou University. 
 His research interests include neutrino physics\, particle physics phenome
 nology\, and new physics models. During his Ph.D. studies\, he worked on n
 eutrino non-standard interactions\, neutrino-antineutrino oscillations\, l
 epton number violation\, and the muon anomalous magnetic moment. His work 
 has been published in journals including Physics Letters B and Journal of 
 High Energy Physics. He was selected for the Tsung-Dao Lee PhD Program at 
 Shanghai Jiao Tong University and served as the principal investigator of 
 an NSFC Basic Research Program for Young Students (PhD students) project.\
