Light Neutralino Dark Matter in the MSSM

Friday October 21st, 14:30hs - Seminar room

Speaker: Lorenzo Calibbi (Max Planck Institut fuer Physik, Munich)


We investigate the constraints to the light neutralino dark matter scenario in the minimal supersymmetric standard model from available experimental observations such as decays of B and K meson, relic dark matter abundance, and the search for neutralino and Higgs production at colliders.

Boosted objects and subjects at the LHC

Tuesday October 18th, 15:30 hs - Seminar room

Speaker: Jon Butterworth UCL (London)


The Large Hadron Collider has been providing 7 TeV proton-proton collisions for a year an a half, exploring physics above the scale of electroweak unification. Uniquely at these energies, particles with masses at the electroweak scale - W,Z,top and possibly the Higgs boson - can be produced well above threshold, and thus with high Lorentz boosts.

Counting Invisible Particles at the LHC

Friday October 14th, 14:40hs - Seminar room

Speaker: Rakhi Mahbubani (CERN)


We suggest trying to count the number of invisible particles produced in missing energy events at the LHC, arguing that multiple production of such particles provides evidence that they constitute stable Dark Matter and that counting them could yield further insights into the nature of Dark Matter.

Extraordinary phenomenology from warped flavor triviality

Wednesday October 5th, 15:00hs - Seminar room

Speaker: Cedric Delaunay (CERN)


We present a class of warped models, dubbed Flavor Triviality (FT), where the SM flavor hierarchies are determined by UV physics. These models allow for a KK-gluon mass as low as O(2)TeV which is consistent with EWPTs.

ATLAS Selected Results

Friday September 23rd, 14:30hs - Seminar room


Speaker: Mario Martinez (IFAE)

Abstract: An overview is given of some of the most interesting results presented at the summer conferences by the ATLAS Experiment, using proton-proton collisions at sqrt(s) = 7 TeV and based on the 2010 and 2011 datasets. Special emphasis is put on the search for new physics beyond the Standard Model and the Higgs boson.



Reconciling thermal leptogenesis and gravitino by the strong CP problem and its observation

Friday September 16th, 14:30hs - Seminar room


Speaker:  Jasper Hasenkamp (University of Hamburg)


A consistent cosmology has to explain the observed matter composition of the Universe and should enable solutions to all problems of the Standard Model.

Review of the situation with neutrino mass models and prospects – emphasis on S(3) symmetry

Monday, September 19th at 12:00 - Seminar room
