Abstract During the first LHC long shutdown, the CMS and ATLAS collaborations finalized the study of the 8TeV data collected in 2012. Within the impressive amount of results produced, a few searches for new physics show a “coherent” small tension with the prediction from the Standard Model. While the significance is still too small to allow any conclusion, some of … Read More
Even though no new particles were discovered at the LHC so far, LHCb found deviations from the standard model predictions in b->smumu transitions with a significance above the 4 sigma level. Furthermore, CMS found hints for the decay h->taumu and BaBar, BELLE and LHCb observed hints for lepton flavour non-universality in tauonic B decays. In this talk I review various … Read More
Abstract: Supersymmetry (SUSY) is a promising candidate beyond the standard model. In this talk, we first review the present status of SUSY at the LHC. The observed Higgs mass forces us to accept fine-tuning or extend the Higgs sector of the minimal model. We here pursue the latter possibility and lift the Higgs mass by partial compositeness where the Higgs … Read More
Abstract: A signal of dark matter annihilation in our Galaxy could provide the first window into the missing matter of the Universe. I plan to discuss the current status of such searches with data from the Fermi Large Area Telescope, and their implications for models of dark matter. My primary focus will be on the development of a new analysis … Read More
Abstract: I will discuss some of the new physics scenarios which could be probed at the long-baseline neutrino facility (LBNF) and the deep underground neutrino experiment (DUNE). A near detector at LBNF could probe the existence of a leptophobic portal to a dark sector via a $Z’$ beyond current constraints. The DUNE far detector data, on the other hand, could … Read More
Abstract: The standard LCDM paradigm has been phenomenally successful on many fronts. In particular, all predictions with respect to the overall cosmology and structure on large scales have proven accurate. But on small scales – kilo parsecs and less – the hierarchical model has been neither confirmed nor refuted. For example, dark matter cusps are predicted, but observations do not … Read More
We study how, as a result of the scanning of supersymmetry breaking during the cosmological evolution, a relaxation mechanism can naturally determine a hierarchy between the weak scale and the masses of supersymmetric particles. Supersymmetry breaking is determined by QCD instanton effects, in an extremely minimal setup in which a single field drives the relaxation and breaks supersymmetry. Since gauginos … Read More
