Pion content of the nucleon as seen in the NA51 Drell-Yan experiment
/ Authors
/ Abstract
In a recent CERN Drell-Yan experiment the NA51 group found a strong asymmetry of −u and ¯d densities in the proton atx ≌ 0.18. We interpret this result as a confirmation of the pion-induced sea in the nucleon.
