Electroweak phase transition in the economical 3-3-1 model
We consider the EWPT in the economical 3-3-1 (E331) model. Our analysis shows
that the EWPT in the model is a sequence of two first-order phase transitions,
at the TeV scale and at the
GeV scale. The EWPT is triggered by the new
bosons and the exotic quarks; its strength is about if the mass ranges
of these new particles are . The
EWPT is strengthened by only the new bosons; its
strength is about if the mass parts of , and
are in the ranges . The
contributions of and to the strengths of both EWPTs may
make them sufficiently strong to provide large deviations from thermal
equilibrium and B violation necessary for baryogenesis.Comment: 17 pages, 9 figure
