SUMMARY:Search for signatures of dark matter induced nucleon decay\, T
 heory Seminar (High Energy/Cosmology)\, Yue Zhao\, Stanford University
DESCRIPTION:If dark matter (DM) carries baryon and/or lepton number\, 
 a DM particle may annihilate with a nucleon by flipping to anti-DM. We
  introduce a model where DM is asymmetric and carries B and L as -1/2.
  It can annihilate with a nucleon to meson\, lepton and anti-DM. Such 
 signal may be observed in proton decay experiments\, similar signal ha
 s been studied in detail in arXiv:1008.2399\, though in a different ch
 annel. If DM is captured in the Sun\, the DM induced nucleon decay cou
 ld generate a large flux of neutrinos\, which could be observed in neu
 trino experiments. Furthermore\, the anti-DM particle in the final sta
 te obtains a relatively large momentum (few hundred MeV)\, and escape 
 the Sun. These fast anti-DM particles could also induce interesting si
 gnals in various ground experiments.
