Title:     Neutrino Mass, Sneutrino Dark Matter and Signals of Lepton Flavor Violation in the MRSSM

Abstract: I will discuss the phenomenology of mixed-sneutrino dark matter
in the Minimal R-symmetric Supersymmetric Standard Model (MRSSM). The
MRSSM was proposed as an alternative solution to the supersymmetric flavor
problem with O(1) flavor violation in the sfermion masses. Mixed
sneutrinos fit naturally within the MRSSM, as the smallness (or absence)
of neutrino Yukawa couplings singles out sneutrino A-terms as the only
ones not automatically forbidden by R-symmetry. A study of randomly
generated sneutrino mass matrices is performed, with limits from DM relic
density, direct detection experiments and neutrino oscillation data
constraining the properties of a viable mixed sneutrino LSP. In addition,
mixed sneutrinos can lead to striking signals of e-$\mu$ flavor violation
at the LHC.
