The Drell–Yan process occurs in high energy hadron –hadron scattering. It takes place when a quark of one hadron and an antiquark of another hadron annihilate, creating a virtual photon or Z boson which then decays into a pair of oppositely-charged leptons.
Em física de partículas, o processo Drell-Yan é a criação de um fóton virtual a partir da combinação de pártons de dois hádrons que colidem. O subsequente "decaimento" deste fóton em um par de léptons termina a caracterização do processo.
Fermilab E-906/SeaQuest is a particle physics experiment which will use Drell–Yan process to measure the contributions of antiquarks to the structure of the proton or neutron and how this structure is modified when the proton or neutron is included within an atomic nucleus.
18 de fev. de 2021 · The Drell-Yan process provides important information on the internal struc- ture of hadrons including transverse momentum dependent parton distribution functions (TMDs). In this work we present calculations for all leading twist structure functions de- scribing the pion induced Drell-Yan process.

22 de jan. de 2019 · This article presents the review of the current understanding on the pion-nucleon Drell-Yan process from the point of view of the TMD factorization. Using the evolution formalism for the unpolarized ...
1 de nov. de 1982 · The Drell-Yan process is an electromagnetic effect in which a quark and antiquark from a pair of interacting hadrons annihilate to give a lepton pair. A brief description of hadron structure and the parton model is given to provide a necessary background.
We study nuclear dependencies of azimuthal asymmetries in the Drell-Yan lepton pair production in nucleon-nucleus collisions with polarized nucleons. We use the “maximal two-gluon correlation approximation,” so that we can relate the transverse-momentum-dependent quark distribution in a nucleus to that in a nucleon by a con-
