Research

The Higgs boson has been discovered and a Nobel Prize has been awarded. The absence of other discoveries at the LHC has made life difficult for particle theorists. Here are my unorthodox predictions for a brighter future.
  • Deviations from standard model predictions for the Higgs will eventually be established.
  • The Higgs boson will be just one manifestation of new TeV scale physics.
  • New heavy chiral fermions will be found.
  • The concept of naturalness will once again come back into fashion.
Here are my equally unorthodox views regarding the ultimate theory of particle physics.
  • It contains no elementary scalar fields.
  • It contains no dimensionful parameters.
  • It is a massless gauge theory of chiral fermions.
  • All masses are generated dynamically.
There is still much to learn and to appreciate about such theories.
