SUMMARY:Discrete Abelian symmetries in the MSSM and its extensions\, T
 heory Seminar (High Energy/Cosmology)\, Volodymyr Takhistov\, Universi
 ty of California\, Irvine
DESCRIPTION:Discrete symmetries play a major role in particle physics.
  With supersymmetry being one of the most well motivated extensions of
  the Standard Model\, discrete symmetries have been employed in  the c
 ontext of minimal supersymmetric Standard Model (MSSM) to resolve vari
 ous issues such as fast proton decay and the mu-problem. We systematic
 ally explore anomaly free and phenomenologically viable discrete Abeli
 an (R-)symmetries for the MSSM\, considering both R-parity conserving 
 as well as violating (RPV) scenarios. Among the new solutions that we 
 obtain\, some RPV models are found to be compatible with the Pati-Sala
 m unification and some favor Dirac neutrino mass. Additionally\, we pr
 esent a novel general algorithm for identifying a maximal discrete sym
 metry for a given particle content and a set of constraints.<br>
\nWe 
 describe how such discrete symmetries may be used as a basis for const
 ruction of more complete models\, which also address baryogenesis and 
 flavor sector. Since proton decay is one of the most severe constraint
 s  for such models\, we will briefly mention some of the novel proton 
 decay searches at the Super-Kamiokande experiment. Finally\, we will a
 lso show how the lack of stabilizing discrete Z3 symmetry in the conte
 xt of lepton-flavored dark matter (DM) models can lead to interesting 
 DM decay channels.
