Multidimensional gravity

Modern cosmology inevitably involves physics, which is not described by the standard model of elementary particles. The particle physics models, presenting possible candidates for dark matter and physical basis for dark energy, inflation and baryosynthesis, or leading to cosmological consequences are the subjects of this topic.

Questions to Gia Dvali

New postby Maxim Khlopov on Thu 23 Apr 2009 18:50

Questions and comments after VIA lecture by Gia Dvali on 13.06.2008 (see record for answers):
Konstantin Belotsky (MIFI, Cosmion, Moscow): (6/13/2008 17:07) how could ordinary particles be produced in our Universe in much greater amount with respect to other SM copies?
Richard Weiner: Does your approach imply that you populate the 'desert' between the weak scale and the Planck mass by 10^32 species of new particles?
Richard Weiner: Is your new particle species space uniformly populated?
Richard Weiner: (Wouldn't there be in the new space a desert and thus a new hierarchy problem?
Konstantin Belotsky (MIFI, Cosmion, Moscow): In conituation of my previous question:if inflation for our particles ends later than for other SM copies, then inflation for many of SM copies should end almost simultaneously in order different SM copies dilute each other in space.
Konstantin Belotsky (MIFI, Cosmion, Moscow): thank you very much for very interesting and illustrative report!
