Beyond The Standard Model
The Standard Model of particle physics is amazingly successful, yet it leaves many basic questions unanswered. From bizarre, unexplained parameters such as the cosmological constant, Higgs mass, or neutron electric dipole moment to the lack of explanation for observed phenomena such as dark matter and baryogenesis, there is strong evidence that the Standard Model must be extended. At SITP we have focused on finding solutions to these open problems to discover what these hints tell us about the underlying laws of physics.
