Quark Substructure
The hypothesis that quarks are not fundamental, point-like particles but instead possess an internal composition of even smaller constituents.
Theoretical Framework
- Under the standard-model, quarks are classified as elementary particles with no known internal structure.
- Any evidence of internal complexity would necessitate the development of physics beyond the standard-model.
Experimental Investigations
- High-energy particle collisions are used to probe for deviations from point-like behavior:
- LHC CMS Experiment Tests for Quark Substructure: Analyzes data from the CMS Experiment at the LHC to investigate whether quarks possess any internal structure or if there are even smaller particles beneath them.
