SUMMARY:Heavy Neutrinos and Where to Find Them\, Theory Seminar (High 
 Energy/Cosmology)\, Kevin Kelly\, Fermilab
DESCRIPTION:The discovery of neutrino oscillations led to a new unders
 tanding that neutrinos have mass\, which requires physics beyond the S
 tandard Model. One well-motivated and well-studied solution is that ri
 ght handed neutrinos exist and interact in a way that generates light 
 neutrino masses. Moreover\, if these new neutrinos are “Heavy”\, t
 here is potential for explaining why the Standard Model neutrinos are 
 so much lighter than the charged leptons and quarks. I will summarize 
 current searches for these heavy neutrinos across a wide range of mass
 es and then focus on a particular regime of interest — GeV-scale Hea
 vy Neutrinos. I will demonstrate how neutrino oscillation experiments 
 can serve as a great environment to find these hypothetical particles 
 in the coming decade. If we are lucky enough to discover these particl
 es\, then understanding them will become of paramount importance to th
 e particle physics community. I will show strategies for exploring two
  specific characteristics of these heavy neutrinos by studying their d
 ecays: whether or not Lepton number is conserved (or whether they are 
 Dirac or Majorana fermions)\, and what types of particle/particles med
 iate their interactions.
