G.Ballesteros:SMASH- unifying inflation, axions, ...
Posted: Fri 10 Feb 2017 17:35VIA lecture by Guillermo Ballesteros "SMASH: how to unify inflation with the axion, dark matter, baryogenesis and the see-saw" was given on 10.02.2017. It's presentation is attached and the record is in VIA library

The following questions were put in discussion:
Albino Hernandez: within your approach, are there singlet neutrinos which do not mix with the SM ones?
Houri Ziaeepour: Thank you. A comment ad a question: The mass of axion is in SMASH seems to be in conflict with observations which needs CDM. Question: Can the non-minimal coupling to gravity be effective ?
Alex Dias: Guillermo, Very nice work. Thanks! My question is is: Is it still possible to have inflation in your model for other values of f_A? I mean lower values of f_A? Because the axion could have a large mass.
Houri Ziaeepour: No. It is too light and can be considered as warm DM.
Houri Ziaeepour: There is strong constraint on modified GR. Thus the nonminimal interaction should be an effective effect of interactions.
