Welcome to HPNP2019

The 4th International Workshop on "Higgs as a Probe of New Physics" (HPNP2019) will be hosted by Osaka University. The workshop will be held in 18.-22. February 2019 on Toyonaka Campus of Osaka University, Toyonaka, Japan.

By the discovery of a Higgs boson in 2012, the standard model was confirmed to give a good description for most of the phenomena below the electroweak scale. In spite of the success of the standard model, the nature of the Higgs sector and the dynamics behind the electroweak symmetry breaking are still mystery. On the other hand, there are phenomena which cannot be explained in the standard model, such as neutrino oscillation, existence of dark matter, baryon asymmetry of the Universe and cosmic inflation. It is clear that the new physics beyond the standard model is necessary.

The LHC has been revealing physics at the terascale and will be upgraded to the High-Luminosity LHC. Meanwhile, SuperKEKB will explore well beyond the terascale via heavy flavor decays. The Laser Interferometer Space Antenna (LISA), aimed at detecting gravitational waves from the early Universe, has been approved. The synergy of these upcoming experiments as well as future lepton colliders such as ILC, FCCee, CEPC and CLIC, and also various cosmological observations will bring us insights into the nature of new physics. Therefore, it is a good time to discuss the physics role of the Higgs sector and its relation to the physics beyond the standard model.

The aim of HPNP2019 is to bring together Higgs related physicists from around the world to discuss the relation between Higgs physics and models beyond the Standard Model.

The topics of the workshop will be

  • Determination of the Shape of the Higgs Sector from Experiments
  • Physics of Extended Higgs Sectors
  • New Paradigms and Higgs Physics (SUSY, Composite Higgs, Scale Invariance, Extra Dim, ...)
  • Dynamics behind Electroweak Symmetry Breaking
  • Higgs Physics and Flavor Physics/Neutrinos Physics/Dark Matter
  • Electroweak Phase Transition and Higgs Physics
  • Higgs Inflation, other Cosmological Implications
  • Higgs and Planck Scale Physics
