Do the E866 Drell Yan data change our picture of the chiral structure of the nucleon ?
N. N. Nikolaev, W. Schäfer, A. Szczurek +1
We revisit the evaluation of the pionic mechanism of the -asymmetry in the proton structure function. Our analysis is based on the extended AGK unitarity relation…
The Reaction and the Validity of the OZI Rule
J. Haidenbauer, K. Nakayama, J. W. Durso +2
The reaction is investigated within a relativistic meson-exchange model of hadronic interactions. The possibility of extracting the coupling constant from a stu…
Enhancement of Threshold Cross Sections by In-Medium Final State Interactions
R. Rapp, J. W. Durso, Z. Aouissat +5
We address the problem of pion production in low energy -nucleus collisions. For the production mechanism we assume a simple model consisting of a coherent sum of single pion ex…
Role of the isobar in the reaction near threshold
C. Hanhart, J. Haidenbauer, O. Krehl +1
A model calculation for pion production in nucleon-nucleon collisions is presented. Direct production, pion rescattering and contributions from pair diagrams are taken into account…
Semi-inclusive Pion Production and the d/u Ratio
W. Melnitchouk, J. Speth, A. W. Thomas
We explore the feasibility of directly extracting the large-x valence d/u ratio through a measurement of pions in the current fragmentation region of semi-inclusive deep-inelastic…
Dynamics of Light Antiquarks in the Proton
W. Melnitchouk, J. Speth, A. W. Thomas
We present a comprehensive analysis of the recent data from the E866 experiment at Fermilab on Drell-Yan production in pD and pp collisions, which indicates a non-trivial x-depende…
