One of the simplest models of dark matter is where a scalar singlet field S comprises some or all of the dark matter and interacts with the standard model through an vertical bar H vertical bar…

A bstractMotivated by 3.9σ evidence of a CP-violating phase beyond the standard model in the like-sign dimuon asymmetry reported by D∅, we examine the potential for two Higgs doublet models (2HDMs)…
Electroweak baryogenesis and dark matter from a singlet Higgs
- J. Cline, K. Kainulainen
- Physics
- 15 October 2012
If the Higgs boson H couples to a singlet scalar S via ?m|H|2S2, a strong electroweak phase transition can be induced through a large potential barrier that exists already at zero temperature. In…

Electroweak baryogenesis at high bubble wall velocities
- J. Cline, K. Kainulainen
- PhysicsPhysical Review D
- 2 January 2020
It is widely believed that electroweak baryogenesis should be suppressed in strong phase transitions with fast-moving bubble walls, but this effect has never been quantitatively studied. We rederive…
Improved Electroweak Phase Transition with Subdominant Inert Doublet Dark Matter
- J. Cline, K. Kainulainen
- Physics
- 11 February 2013
The inert doublet dark matter model has recently gained attention as a possible means of facilitating a strongly first order electroweak phase transition (EWPT), as needed for baryogenesis. We extend…
A New Source for Electroweak Baryogenesis in the MSSM
- J. Cline, K. Kainulainen
- Physics
- 25 February 2000
One of the most experimentally testable explanations for the origin of the baryon asymmetry of the universe is that it was created during the electroweak phase transition, in the minimal…
Self-interacting dark matter and cosmology of a light scalar mediator

- 17 July 2015
The case where dark matter has a self-interaction strength h Vi=m 0:1 1 cm 2 =g is strongly constrained, in particular by the Big Bang Nucleosynthesis, which can be alleviated by introducing a new light sterile neutrinoN.
