Bethe Colloquium by Gilad Perez

June 2016
Poster Perez

June's Bethe Colloquium will take place on June 2nd
(4:15 pm) in Hörsaal I:

  • Gilad Perez (Weizmann Institute, Rehovot)
  • Probing the atomic Higgs force
  • Hörsaal I, Physikalisches Institut

Abstract: After the discovery of the Higgs particle at the LHC, the Higgs mechanism is expected to account for the masses of the fundamental particles. We argue that, while this is true for the electroweak gauge bosons, we are still in the dark regarding the origin of the charged fermions masses, in particular those of electron, up and down quark. It motivates us to propose a non-collider approach to probe Higgs boson couplings to these matter constituents via precision measurement of isotope shifts in atomic clock transitions. We present an experimental method which competes with and potentially surpasses the LHC in bounding the Higgs-to-light-fermion couplings. Better knowledge of the latter is an important test of the Standard Model and could lead to an alternative understanding of the flavor puzzle (the fact that the fermion masses span five orders of magnitude in scale). We will then discuss how to translate the above (potential) fantastic sensitivity to constrain the presence of heavy new particles that are well beyond the reach of near future accelerators.

Bethe Colloquium by Gabrijela Zaharijas

June 2016
Poster Perez

June's 2nd Bethe Colloquium will take place on June 16nd
(4:15 pm) in Hörsaal I:

  • Gabrijela Zaharijas (Nova Gorica)
  • Dark Matter search with the Fermi Large Area Telescope
  • Hörsaal I, Physikalisches Institut

Abstract: High energy gamma-rays are one of the most promising tools to constrain or reveal the nature of dark matter. During the almost eight years of the Fermi satellite mission, the data from its Large Area Telescope (LAT) were used to set constraints on the dark matter cross section to various particle channels which now cut well into the theoretically motivated region of the parameter space. In this talk I will describe methods used to search for evidence of dark matter with the LAT, and review the status of the searches. Special attention will be given to the latest indications of the origin of the unaccounted gamma-ray excess at few GeV in the Fermi-LAT data in the region around the Galactic Center, which steered lots of attention as it was shown to be consistent with putative signals of WIMP dark matter particles. Finally I will discuss projections of the expected sensitivities with continued LAT data taking.
