20. Leptoquark mass limit in SU(5)

Prof. Ilja Doršner (University of Sarajevo)

15/04/2013, 16:35

I address the issue of model dependence of partial proton decays due to exchange of a single scalar leptoquark within a minimal viable SU(5) framework. The minimal setup predicts a flavor part of the proton decay widths for channels with anti-neutrinos in the final state to depend solely on the known masses and mixing parameters of the quark sector and one extra phase. I accordingly establish...

23. A natural framework for baryonic R-parity violation in GUT

We investigate the possibility of obtaining large (up to O(1)) R-parity- and baryon-number- violating couplings in supersymmetric GUT. Since quarks and leptons are embedded into the same grand-unified multiplets, the natural expectation is that baryonic R-parity violation is always associated with similar-size lepton-number-violating couplings. Being the simultaneous presence of both types of...

47. Gauge Mediation beyond MFV

Robert Ziegler (TUM)

I will discuss a modification of Gauge Mediation in which the messenger sector couples directly to the MSSM. These couplings are controlled by the same dynamics that explain the flavor hierarchies, and therefore are parametrically as small as the Yukawas. This setup gives rise to an interesting SUSY spectrum that is calculable in terms of a single new parameter. Due to large A-terms, the model...

11. Three-generation baryon and lepton number violation at the LHC

Gauthier Durieux (CP3 - UCLouvain)

15/04/2013, 18:03

While stringent constraints have been obtained at low energies, systematic and direct tests of the baryon and lepton number conservations have not been carried out at the current energy frontier. We observe that the flavour symmetries of the Standard Model gauge sector, broken as they are in the Standard Model Yukawa one, naturally suppress baryon and lepton number violation at low energy and,...
