TY - JOUR AU - Barenboim, G. AU - Rasero, J. PY - 2012 DA - 2012// TI - Electroweak baryogenesis window in non standard cosmologies T2 - J. High Energy Phys. JO - Journal of High Energy Physics SP - 028 EP - 20pp VL - 07 IS - 7 PB - Springer KW - Cosmology of Theories beyond the SM KW - Beyond Standard Model KW - Neutrino Physics AB - In this work we show that the new bounds on the Higgs mass are more than difficult to reconcile with the strong constraints on the physical parameters of the Standard Model and the Minimal Supersymmetric Standard Model imposed by the preservation of the baryon asymmetry. This bound can be weakened by assuming a nonstandard cosmology at the time of the electroweak phase transition, reverting back to standard cosmology by BBN time. Two explicit examples are an early period of matter dominated expansion due to a heavy right handed neutrino (see-saw scale), or a nonstandard braneworld expansion.
