Parton
In
particle physics, the
parton was a hypothetical
fundamental particle considered, in the 'parton model' of
strong interactions, to be a constituent of the
hadron. In the
1970s,
quantum chromodynamics showed that hadrons are composed of
quarks, but the parton model is still used to explain some aspects of short-distance interactions.
