Flavon-assisted leptogenesis reproduces the baryon asymmetry at TeV scales
A theoretical study finds that flavon fields can enable TeV-scale leptogenesis that reproduces the observed baryon asymmetry while remaining compatible ...
A Single Sterile Neutrino Could Be Dark Matter and Help Build the Universe’s Matter
A new theoretical analysis shows that the lightest of three right-handed neutrinos in the scotogenic model can act as dark ...
How the Early Universe May Have Handed Matter Its Spin
