Probing the baryogenesis and dark matter relaxed in phase transition by gravitational waves and colliders
The cosmological phase transition with Q-balls production mechanism can
explain the baryogenesis and dark matter simultaneously, where constraints on
dark matter masses and reverse dilution are significantly relaxed. We study how
to probe this scenario by collider signals at QCD next-to-leading order and
gravitational wave signals.Comment: 22 pages,9 figures,4 tables, published in Phys.Rev.
Electroweak baryogenesis in the framework of the effective field theory
We study the electroweak baryogenesis in the framework of the effective field
theory. Our study shows that by introducing a light singlet scalar particle and
a dimension-5 operator, it can provide the strong first order phase transition
and the source of the CP-violation during the phase transition, and then
produce abundant particle phenomenology at zero temperature. We also show the
constraints on the new physics scale from the observed baryon-to-photon ratio,
the low-energy experiments, and the LHC data.Comment: 12 pages, 5 figures, 1 table; version published in Phys.Rev.
