DESCRIPTION:Speakers: Kaladharan Ajay (ICTP-AP)\nMechanisms that generate 
 large neutrino magnetic moments consistent with observed neutrino masses t
 ypically decouples the mechanism responsible for neutrino mass and the neu
 trino magnetic moment. In this letter\, we propose a novel framework to ex
 plain neutrino mass while accommodating a large magnetic moment for the ac
 tive neutrinos. The SM neutrinos get mass via the inverse seesaw mechanism
 . We introduce a novel horizontal-like softly broken $SU(2)_N$ symmetry in
  which SM particles are singlets. In the $SU(2)_N$ symmetric limit\, one o
 f the fermionic states participating in the inverse seesaw can possess a l
 arge magnetic moment while remaining massless. The $SU(2)_N$ symmetry is s
 oftly broken\, and SM neutrinos obtain nonzero neutrino mass and large mag
 netic moment via sterile-active neutrino mixing. The active neutrinos can 
 exhibit transition magnetic moments as large as $\\mathcal{O}(10^{-11}\\mu
 _B)$.\n\nhttps://indico.itp.ac.cn/event/427/contributions/2989/
