Impact of a complex singlet: From dark matter to baryogenesis

  title={Impact of a complex singlet: From dark matter to baryogenesis},
  author={Minyuan Jiang and Ligong Bian and Wei-Chih Huang and Jing Shu},
With the assistance of a complex singlet, and a effective operator involving CP violations, the dark matter relic abundance and baryon asymmetry of the universe (BAU) are accommodated simultaneously. The mechanism Electroweak baryogenesis (EWBG) is studied systematically: from the necessary condition strong first order electroweak phase transition (SFOEWPT) to BAU generation. The SFOEWPT takes one step or two steps due to the dynamics of the energy gap of the Electroweak vacuum and the vacuum… 
The Higgs Portal and Cosmology
Higgs portal interactions provide a simple mechanism for addressing two open problems in cosmology: dark matter and the baryon asymmetry. In the latter instance, Higgs portal interactions may contain
Phase transition gravitational waves from pseudo-Nambu-Goldstone dark matter and two Higgs doublets
Abstract We investigate the potential stochastic gravitational waves from first-order electroweak phase transitions in a model with pseudo-Nambu-Goldstone dark matter and two Higgs doublets. The
Thermal resummation and phase transitions
The consequences of phase transitions in the early universe are becoming testable in a variety of manners, from colliders physics to gravitational wave astronomy. In particular one phase transition
Detectable gravitational waves from very strong phase transitions in the general NMSSM
We study the general NMSSM with an emphasis on the parameter regions with a very strong first-order electroweak phase transition (EWPT). In the presence of heavy fields coupled to the Higgs sector,
On the perturbative expansion at high temperature and implications for cosmological phase transitions
We revisit the perturbative expansion at high temperature and investigate its convergence by inspecting the renormalisation scale dependence of the effective potential. Although at zero temperature
Triple Higgs boson production at the Large Hadron Collider with Two Real Singlet scalars
Abstract We investigate the production of three Higgs bosons in the Two Real Singlet extension of the Standard Model, where the scalar sector is augmented by two additional real scalar fields which
Two-real-scalar-singlet extension of the SM: LHC phenomenology and benchmark scenarios
We investigate the LHC phenomenology of a model where the Standard Model (SM) scalar sector is extended by two real scalar singlets. A $${{\mathbb {Z}}_2} \otimes {{\mathbb {Z}}_2} '$$ Z 2 ⊗ Z 2 ′
Testing clockwork axion with gravitational waves
We investigate the gravitational waves (GWs) produced from the Peccei-Quinn (PQ) phase transition associated with the clockwork axion. The PQ phase transition can be first-order when the dimension-6
The gravitational waves from the collapsing domain walls in the complex singlet model
We study the CP domain walls and the consequent gravitational waves induced by the spontaneous breaking of the CP symmetry in the complex singlet extension to the Standard Model. We impose the
Stop-Catalyzed Baryogenesis Beyond the MSSM
Nonminimal supersymmetric models that predict a tree-level Higgs mass above the minimal supersymmetric standard model (MSSM) bound are well motivated by naturalness considerations. Indirect
