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

2 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

3 Example: Chaotic Models

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

5 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

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

7 REHEATING: Non-Perturbative Production

9 REHEATING: Combined Preheating

11 REHEATING (II): BackReaction

12 REHEATING: CONCLUSIONs

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

14 REHEATING (I): (Succesive) Instant Preheating
