Electroweak Phase Transition in the munuSSM
  An extension of the MSSM called the munuSSM does not allow a conventional
thermal leptogenesis scenario because of the low scale seesaw that it utilizes.
Hence, we investigate the possibility of electroweak baryogenesis.
Specifically, we identify a parameter region for which the electroweak phase
transition is sufficiently strongly first order to realize electroweak
baryogenesis. In addition to transitions that are similar to those in the
NMSSM, we find a novel class of phase transitions in which there is a rotation
in the singlet vector space.
