چکیده
We investigate how Drell-Yan processes can be used to measure the magnitude of flavor symmetry violation in the proton sea. We examine the utility of the following beams: protons, charged pions, and charged kaons. In each case we present an approximate expression for the Drell-Yan asymmetry. Using currently available parton distributions, we locate those kinematic regions which provide the greatest information on the quantity d̄(x)− ū(x). If sufficiently intense K+ beams were available, they could provide an efficient measurement of this quantity. Finally we present and discuss sets of sum rules for the Drell-Yan processes.

متن کاملTesting the meson cloud in the nucleon in Drell-Yan processes
We discuss the present status of the u − d asymmetry in the nucleon and analize the quantities which are best suited to verify the asymmetry. We find that the Drell-Yan asymmetry is the quantity insensitive to the valence quark distributions and very sensitive to the flavour asymmetry of the sea. We compare the prediction of the meson cloud model with different experimental data including the F...
متن کاملMesonic and Binding Contributions to the Nuclear Drell-yan Process
We have evaluated the Drell-Yan cross section in nuclei paying special attention to the meson cloud contribution from pion and ρ-meson, for which an accurate calculation using the meson nuclear spectral functions is used. Similarly, the nucleonic contribution is evaluated in terms of a relativistic nucleon spectral function. Fair agreement with experiment is found for different nuclei and the r...
متن کاملApplications of KP Nuclear Parton Distributions
We review the nuclear parton distribution functions computed on the basis of our microscopic model taking into account a number of nuclear effects including Fermi motion and nuclear binding, nuclear meson-exchange currents, off-shell corrections to bound nucleon distributions and nuclear shadowing. We discuss applications to a number of different processes including leptonnucleus deep inelastic...
متن کاملGround state correlations in Deep Inelastic Scattering and the
Such high energy processes as deep inelastic scattering (DIS) and Drell-Yan heavy lepton pair production are among the most important tools to probe the quark and gluon interaction. We calculated non-perturbative corrections to the LO cross section formulae for DIS and the Drell-Yan process. The interaction of partons was taken into account via dressing the incoming quark lines with spectral fu...
