 Deep inelastic scattering

Scattering that resolves the constituents of a hadron at large spacelike momentum transfer, with an inclusive sum over final hadron states.

Deep inelastic scattering (DIS) is a high-energy particle physics process that provides insights into the internal structure of protons, neutrons, and other hadrons. It involves the scattering of high-energy electrons (or other leptons) off of protons or neutrons, where the energy of the lepton is high enough that it can probe the internal quark and gluon constituents of the target hadron.
