In physics, the Standard Model of particle physics is currently the best description of all experimental data.[1] Nevertheless, there are reasons to think that there are phenomena that are not accurately described by this theory and "Beyond the Standard Model" physics studies possible extensions to the Standard Model that will be probed in up-coming experiments.
There are several areas where "Beyond the Standard Model" physics focuses:
- the hierarchy problem
- the missing matter problem (dark matter and dark energy)
- the cosmological constant problem
- the strong CP problem
In addition to these subjects, there are also attempts at relating different phenomena and parameters to a more fundamental theory. A partial classification of these attempts are
- gauge coupling unification
- a theory of quark masses and mixings
- a theory of neutrino masses and mixings
