The νMSM (ν Minimal Standard Model) extends the Standard Model by adding three right-handed neutrinos with masses below the electroweak scale. This model can explain neutrino oscillations, dark matter, and the baryon asymmetry of the universe. The νMSM includes 18 new parameters, with three being Majorana masses and the rest in the Yukawa matrix. The model is consistent with neutrino oscillation data and experimental constraints. The νMSM can account for dark matter through the lightest sterile neutrino, which is identified as the "dark" neutrino. The model also provides a mechanism for baryon asymmetry through CP-violating sterile neutrino oscillations, which generate a lepton asymmetry that is converted into a baryon asymmetry via sphaleron transitions. The parameters of the νMSM are constrained by dark matter and Big Bang Nucleosynthesis (BBN) requirements, leading to specific values for Yukawa couplings and mixing angles. The model predicts a baryon asymmetry consistent with observations when the heavier sterile neutrinos are highly degenerate in mass. The νMSM is a minimal extension of the Standard Model that can simultaneously explain neutrino oscillations, dark matter, and baryon asymmetry.The νMSM (ν Minimal Standard Model) extends the Standard Model by adding three right-handed neutrinos with masses below the electroweak scale.
