REHEATING in the STANDARD MODEL of PARTICLE PHYSICS DANIEL G. FIGUEROA, UAM-IFT, Madrid 4th Iberian Cosmology Meeting, April 2009, Madrid

BASICS of (P)REHEATING BASICS of (P)REHEATING INITIAL CONDITIONS: t = 0, NO Temperature NO Particles, ONLY Vacuum Energy FINAL CONDITIONS: Thermal Equilibirum, T_RH

Example: Chaotic Models

NON-LINEAR QFT in FRW  NON-PERTURBATIVE, FAR-FROM-EQUILIBRIUM

A Minimal Model HILBERT- EINSTEIN SSB NON- Minimal CST SM:  Good Candidate for Inflation (Bezrukov et al. 07) MODEL Inflationary predictions stable vs Radiative corrections (Starobinsky et al 08, Wilczek et at 08, Bezrukov et al 09) The price to pay:  5 x 10^4 Here I will only focus on REHEATING, after inflation ends

A Minimal Model (GUT), M ~ 10 M 5 p _

REHEATING: Non-Perturbative Production

REHEATING: Combined Preheating

REHEATING (II): BackReaction

REHEATING: CONCLUSIONs

REHEATING (I): Perturbative Higgs Decay  V(  )

REHEATING (I): (Succesive) Instant Preheating
