SiversEffekt
The Sivers effect is a phenomenon in quantum chromodynamics (QCD), the theory describing the strong interaction between quarks and gluons, which are the fundamental constituents of protons and neutrons. It refers to an asymmetry in the distribution of quarks within transversely polarized nucleons (such as protons or neutrons). This effect was first proposed by physicist Mikhail Sivers in 1991 to explain discrepancies observed in deep inelastic scattering experiments.
In deep inelastic scattering, a high-energy lepton (such as an electron or muon) collides with a nucleon,
The Sivers effect is closely related to other transverse spin phenomena, such as the Collins effect, which
Experimental evidence for the Sivers effect has been observed in various high-energy physics experiments, including those
