1303.1452 (Pavel Fileviez Perez et al.)

Baryon Asymmetry and Dark Matter Through the Vector-Like Portal    [PDF]

Pavel Fileviez Perez, Mark B. Wise
A possible connection between the cosmological baryon asymmetry, dark matter and vector-like fermions is investigated. In this scenario an asymmetry generated through baryogenesis or leptogenesis (in the vector-like matter sector) connects the baryon asymmetry to the dark matter density. We present explicit renormalizable models where this connection occurs. These models have asymmetric dark matter and a significant invisible Higgs decay width to dark matter particles is possible. We refer to this type of scenario as the vector-like portal.
