Abstract
We calculate partial Bayes factors to quantify how the feasibility of the constrained minimal supersymmetric standard model (CMSSM) has changed in the light of a series of observations. We take as “training” data the approximate knowledge that was available before LEP, and take our comparison model to be the Standard Model with a simple dark matter candidate. Partial Bayes factors are then computed, using as inference data the LEP2 Higgs constraints, 2011 XENON100 dark matter constraints, 2011 LHC supersymmetry search results, and the early 2012 LHC Higgs search results. We find that LEP and the LHC strongly shatter our trust in the CMSSM, reducing its posterior odds by a factor of approximately two orders of magnitude. This conclusion is robust under variation of priors, but may be avoided if the CMSSM is not required to explain the (g−2) µ anomaly.

| Other | Recent observations suggest that about 95% of the Universe's energy lies in a dark sector. This sector is comprised of dark matter, a form of non-luminous matter, and dark energy whose origin and composition is unknown. Dark matter seems to make up 23% of the Universe and it possibly consists of new exotic particles that interact very weakly with ordinary matter. Dark energy, about 73% of the Universe, is responsible for a mysterious force that is speeding up its expansion. The origin and microscopic composition of dark matter and dark energy are outstanding fundamental problems in physics, and may possibly find a resolution in new theories pointing beyond the standard models of particle physics and cosmology. This prompts a strong connection between particle physics, astrophysics and cosmology. The aim of the meeting is to bring together experts from all around the world to discuss the latest advances in the theoretical, phenomenological and experimental aspects of the field. |
