Tachyonic preheating using 2PI-1/N dynamics and the classical approximation
Alejandro Arrizabalaga, Jan Smit, Anders Tranberg
We study the process of tachyonic preheating using approximative quantum equations of motion derived from the 2PI effective action. The O(N) scalar (Higgs) field is assumed to expe…
Cold Electroweak Baryogenesis
Jan Smit
We present arguments that the CKM CP-violation in the standard model may be sufficient for the generation of the baryon asymmetry, if the electroweak transition in the early univer…
Effective CP violation in the Standard Model
Jan Smit
We study the strength of effective CP violation originating from the CKM matrix in the effective action obtained by integrating out the fermions in the Standard Model. Using result…
Electroweak-scale inflation, inflaton-Higgs mixing and the scalar spectral index
Bartjan van Tent, Jan Smit, Anders Tranberg
We construct a phenomenological model of electroweak-scale inflation that is in accordance with recent cosmic microwave background observations by WMAP, while setting the stage for…
