Update on scalar singlet dark matter
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 barExpand

Expression of Interest for a very long baseline neutrino oscillation experiment (LBNO)
This Expression of Interest (EoI) describes the motivation for and the feasibility studies of a long baseline neutrino oscillation experiment (LBNO) with a new conventional neutrino beamline facilityExpand

Supersymmetric electroweak baryogenesis
We re-examine the generation of the baryon asymmetry in the minimal supersymmetric standard model (MSSM) during the electroweak phase transition. We find that the dominant source for baryogenesisExpand

Neutrino annihilation in hot plasma
Abstract We consider neutrino annihilation in a heat bath, including annihilation via the photon. We show that the annihilation cross section has high and narrow peaks corresponding to a plasmonExpand

The mass-hierarchy and CP-violation discovery reach of the LBNO long-baseline neutrino experiment
A bstractThe next generation neutrino observatory proposed by the LBNO collaboration will address fundamental questions in particle and astroparticle physics. The experiment consists of a farExpand

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. InExpand

Electroweak baryogenesis in two Higgs doublet models and B meson anomalies
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)Expand

Improved Electroweak Phase Transition with Subdominant Inert Doublet Dark Matter
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 extendExpand

Stringent cosmological bounds on inert neutrino mixing
We study neutrino oscillations in the early universe induced by a non-trivial vacuum mixing between an inert SU(2)×U(1) singlet and a weakly interacting doublet neutrino. Excluded regions in theExpand

Light singlet neutrinos and the primordial nucleosynthesis
Abstract We study the production of light SU (2)-singlet neutrinos in the early universe. It is shown that a singlet neutrino v x may be brought into thermal equilibrium if it mixes with an ordinaryExpand
