Flavor Asymmetry in Hyperons and Drell-yan Processes *
نویسنده
چکیده
SU(3), baryon octets and a meson cloud model are compared for the flavor asymmetry of sea quarks in the Σ + , as an example. Large differences are found, especially between SU(3) and the meson cloud model. We suggest Drell-Yan measurements of Σ + −p and Σ + −d to test the prediction of various models. We use the meson cloud model to predict both valence and sea quark distributions.

Proton-deuteron asymmetry in Drell-Yan processes and polarized light-antiquark distributions
We discuss the relation between the ratio of the proton-deuteron (pd) Drell-Yan cross section to the proton-proton (pp) one ∆(T )σpd/2∆(T )σpp and the flavor asymmetry in polarized light-antiquark distributions. Using a recent formalism of the polarized pd Drell-Yan process, we show that the difference between the pp and pd cross sections is valuable for finding not only the flavor asymmetry in...

Exciting and even unexpected results have been presented in the sessions about “polarized lepton nucleon scattering”, at the DIS 99 workshop. Most striking are the presentations of the flavor decomposition of the quark polarization, the first direct observation of a positive gluon polarization in the nucleon and the observation of a double-spin asymmetry in diffractive ρ production. First resul...
متن کاملUsing Drell-Yan Processes to Probe Nucleon and Meson Structure Functions
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 grea...
متن کاملTransversity distributions and Drell-Yan spin asymmetries
We discuss transversity distributions and Drell-Yan transverse double spin asymmetries. First, the antiquark flavor asymmetry ∆ T ¯ u/∆ T ¯ d is discussed by using two different descriptions, a meson-cloud model and a Pauli exclusion model. We find that both calculations produce a significant ∆ T ¯ d excess over ∆ T ¯ u. Next, we study its effects on the transverse spin asymmetry A T T and on t...

Sivers asymmetry, adopted to explain transverse single spin asymmetries (SSA) observed in inclusive pion production, p↑ p → πX and p̄↑ p → πX, is used here to compute SSA in Drell-Yan processes; in this case, by considering the differential cross section in the lepton-pair invariant mass, rapidity and transverse momentum, other mechanisms which may originate SSA cannot contribute. Estimates for ...
