1. Particle Physics and Cosmology
Phase transitions

2. baryogenesis during electroweak phase transition ?

3. Sakharov’s conditions for baryogenesis during electroweak phase transition
baryon number violation interactions ☺
charge conjugation violating interactions ☺
CP – violating interactions ☺
non – equilibrium process ☺

4. baryogenesis during electroweak phase transition ?
strongly first order electroweak phase transition can generate baryon asymmetry if CP violation is sufficiently strong
no efficient baryogenesis for weak first order phase transition, second order phase transition or crossover
presumably too little CP violation in SM ( not definitely settled )

5. electroweak phase transition

13. order of phase transition

17. temperature dependent effective potential
high temperature
expansion

18. next to leading order in high temperature expansion

20. first order cosmological phase transitions

21. chaos in the Universe

25. relics from cosmological first order phase transitions ?

26. electroweak crossover

27. critical mass of the Higgs scalar for the onset of crossover

28. electroweak “phase transition “ in standard model is crossover !
perhaps strong first order transition in
supersymmetric extensions of standard model

29. standard model of particle physics and cosmology
no candidate for dark matter
no baryon asymmetry
no massive neutrinos

30. standard model of particle physics and cosmology
prediction :
present Universe consists of
photons and
massless neutrinos
