WebIOPscience WebThe mechanism of the Drell-Yan process is well understood and the absence of hadronization processes in the final state eliminates the uncertainties caused by the relatively poorly known fragmen- tation functions encountered in semi-inclusive DIS or hadron production in p-p collisions.
WebThe Drell-Yan process occurs as a result of hadron-hadron scattering in which a quark and antiquark of two respective hadrons annihilate. This forms a virtual photon that decays into an oppositely-charged lepton pair. 5 Figure 1: Feynman diagram of the Drell-Yan process.
