We study the impact of recent direct and indirect searches for particle dark matter on supersymmetric models with resonant neutralino- or chargino-driven electroweak baryogenesis (EWB) and heavy sfermions. We outline regions of successful EWB on the planes defined by gaugino and higgsino mass parameters, and calculate the portions of those planes excluded by dark matter search results, and the regions soon to be probed by current and future experiments. We conclude that dark matter searches…

Accidental Supersymmetric Dark Matter and Baryogenesis
We show that ``accidental'' supersymmetry is a beyond-the-Standard Model framework that naturally accommodates a thermal relic dark matter candidate and successful electroweak baryogenesis, including
Light stop mass limits from Higgs rate measurements in the MSSM: is MSSM electroweak baryogenesis still alive after all?
A bstractWe investigate the implications of the Higgs rate measurements from Run 1 of the LHC for the mass of the light scalar top partner (stop) in the Minimal Supersymmetric Standard Model (MSSM).
Electroweak baryogenesis and dark matter from a singlet Higgs
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
Electroweakino constraints from LHC data
A bstractWe investigate the sensitivity of existing LHC searches to the charginos and neutralinos of the MSSM when all the other superpartners are decoupled. In this limit, the underlying parameter
Bubble expansion and the viability of singlet-driven electroweak baryogenesis
A bstractThe standard picture of electroweak baryogenesis requires slowly expanding bubbles. This can be difficult to achieve if the vacuum expectation value (VEV) of a gauge singlet scalar field
Cosmological phase transitions and their properties in the NMSSM
A bstractWe study cosmological phase transitions in the Next-to-Minimal Supersymmetric Standard Model (NMSSM) in light of the Higgs discovery. We use an effective field theory approach to calculate
Lattice study of an electroweak phase transition at mh ≃ 126 GeV
We carry out lattice simulations of a cosmological electroweak phase transition for a Higgs mass mh 126 GeV. The analysis is based on a dimensionally reduced effective theory for an MSSM-like
Review of cosmic phase transitions: their significance and experimental signatures.
TLDR
Different types of phase transitions that can appear in cosmic history, and their applications and experimental signatures in particular in the context of exciting gravitational waves, are reviewed, which could be potentially be constrained by LIGO/VIRGO, Kagra, LISA, and Decigo.

Supersymmetric Origin of Matter
The minimal supersymmetric extension of the standard model (MSSM) can provide the correct neutralino relic abundance and baryon number asymmetry of the universe. Both may be efficiently generated in
Light stop searches at the LHC in events with two b jets and missing energy
We propose a new method to discover light top squarks (stops) in the co-annihilation region at the Large Hadron Collider (LHC). The bino-like neutralino is the lightest supersymmetric particle (LSP)

The focus point region of supersymmetric models is compelling in that it simultaneously features low fine-tuning, provides a decoupling solution to the SUSY flavor and CP problems, suppresses proton
Electroweak baryogenesis and Higgs and stop searches at LEP and the Tevatron
Abstract It has been recently shown that the observed baryon number may originate at the electroweak phase transition, provided that the Higgs boson and the lightest stop are sufficiently light. In

Abstract Electroweak baryogenesis provides an attractive explanation of the origin of the matter–antimatter asymmetry that relies on physics at the weak scale and thus it is testable at present and

Abstract Electroweak baryogenesis is an interesting theoretical scenario, which demands physics beyond the Standard Model at energy scales of the order of the weak boson masses. It has been recently

TLDR
The generality of the arguments rules out any mechanism of electroweak baryogenesis that does not make use of a new source of [ital CP] violation and concludes the QCD damping effects reduce the asymmetry produced to a negligible amount.
