10:00 Neutron-electron EDM correlations in SUSY

In supersymmetry, EDMs of various systems, in particular neutrons and electrons, are correlated. Having observed one of them, one can make predictions for the others, based on the specific SUSY breaking scenario. For example, most SUSY models predict the neutron EDM/the electron EDM ratio to be of order 10. This can be viewed as an indirect signature of supersymmetry. Furthemore, large portions of parameter space accessible to EDM experiments are outside the reach of collider experimets, which makes them particularly interesting.

10:30 On Power and Complementarity of the Experimental Constraints on Seesaw Models

By analysing the class of models based on a U(1) flavour symmetry, we analyse the impact that present lepton flavour and CP violation data - neutrino oscillations, baryon asymmetry of the universe, flavour violations in charged lepton decays and lepton electric dipole moments - have on supersymmetric seesaw theories.

09:30 Reconstructing see-saw models from low energy data

Speaker: Alejandro Ibarra (IFT Madrid)

Slides slides

In this talk we discuss the prospects to reconstruct the high-energy see-saw lagrangian from low energy experiments in supersymmetric scenarios. We show that the model with three right-handed neutrinos could be reconstructed in theory, but not in practice. Then, we discuss the prospects to reconstruct the model with two right-handed neutrinos, which is the minimal see-saw model able to accommodate neutrino observations. We identify the relevant processes to achieve this goal, and discuss the sensitivity of future experiments to them. We find the prospects much more promising and we emphasize in particular the importance of the observation of rare leptonic decays for the reconstruction of the right-handed neutrino masses.

10:00 Minimal Dark Matter

Speaker: Alessandro Strumia (Pisa)

Slides slides  Most recent version of the slides at www.cern.ch/astrumia/MDM.pdf

A few multiplets that can be added to the SM contain a lightest neutral component which is automatically stable and provides allowed DM candidates with a non-standard phenomenology. Thanks to coannihilations, a successful thermal abundance is obtained for well defined DM masses. The best candidate seems to be a SU(2)_L fermion quintuplet with mass 4.5 TeV, accompanied by a charged partner 166 MeV heavier with life-time 1.8 cm, that manifests at colliders as charged tracks disappearing in pi^\pm with 97.7% branching ratio. The cross section for usual NC direct DM detection is sigma_SI = f^2 1.0 10^-43 cm^2 where f ~ 1 is a nucleon matrix element. We study prospects for CC direct detection and for indirect detection.

11:30 Lepton Flavour Violating tau and muon decays induced by SUSY

We present full one-loop predictions of ratios for all LFV tau and muon decays of type l_j -> 3l_i and l_j -> l_i+gamma in the context of the Constrained MSSM with three (Majorana) nu_R and their SUSY partners. We use the seesaw mechanism for neutrino mass generation and choose Universal conditions at M_{GUT}. We study the restrictions on SUSY and seesaw parameters from LFV and neutrino data.

12:30 Large 2HDM(II) one-loop corrections in leptonic tau decays

The one-loop contributions to the branching ratios for leptonic tau decays are calculated in the CP conserving 2HDM(II). We found that these one-loop contributions, involving both neutral and charged Higgs bosons, dominate over the tree-level H^+ exchange, the latter one being totally negligible for the decay into electron.
