Title: Natural explanation for the 130GeV photon line within a vector boson dark matter model
Presenter: Yasaman Farzan (IMP Teheran)
Chair: Nuria Rius (Valencia U)
Abstract: After a brief review of the 130 GeV photon line from the galaxy center, I will present a dark matter model explaining this line. In this model, the dark matter candidate is a vector boson of mass $m_V$ with a dimensionless coupling to the photon and $Z$ boson.
Title: Quo Vadis Higgs?
Presenter: Christoph Grojean (CERN)
Chair: Yann Mambrini (Orsay)
Abstract: After 48 years of desperate searches, the most wanted elementary particle, the Higgs boson, or something that wickedly looks like it, has finally been caught by the ATLAS and CMS experiments.
I shall review what are the implications of this discovery for physics beyond the standard model and cosmology.
Title: The Ghost Supernova Particles
Presenter: Irene Tamborra (Max Planck Munich)
Chair: Stefano Rigolin (Padova U)
Abstract: Despite their extremely weak interactions, neutrinos are crucial to the dynamics of the most spectacular events in our galaxy: the deaths of massive stars in violent supernova explosions.
Presenter: Juan Fraile (Barcelona U)
Chair: Olga Mena (Valencia U)
Abstract:In this talk, after a brief review of the current situation of the Higgs boson analyses at the LHC I will present the updated status of a model independent fit to the Higgs couplings.
Presenter: Alex Merle (Southampton U)
Chair: Silvia Pascoli (Durham U)
Abstract: In this talk, an introduction to keV sterile neutrinos as Dark Matter particles is given. After reviewing the cosmological aspects of (Warm) Dark Matter, I will explain why the topic is interesting for particle physics model building and also point out the differences to ordinary neutrino model building. We will go through a couple of generic models, all of which yield interesting and fundamental connections between the neutrino and the Dark Matter sectors. We finally present some alternative ideas and generalizations.
Presenter: Javier Redondo (TU Munich)
In this webinar we will briefly review the strong CP problem and the solution proposed by Peccei and Quinn, the existence of a new degree of freedom that restores C and P conservation in the colour sector: the axion. Then we will review the cosmology of axions focusing on their role as dark matter (hot and cold), and the perspectives for its discovery.
Presenter: Carlos Frenk (Durham)
The LCDM cosmological model accounts for an impressive array of data on the large-scale structure of the universe. On submegaparsec scales, however, the model cannot be tested with the same degree of rigour as on larger scales where microwave background radiation data and measures of galaxy clustering provide clean and well-understood diagnostics.
Presenter: Juan Herrero
In the first part of the talk, I will review one of the most distinctive signatures of dark matter: the annual modulation that should be detected in direct detection experiments, due to the relative motion of the Earth around the Sun.
