We investigate the information which could be obtained from Drell-Yan
processes with sufficiently intense beams of charged kaons on isoscalar
targets. It is found that combinations of K+ and Kโ Drell-Yan
measurements on isoscalar nuclear targets would allow one to extract the kaon
sea quark distributions. These cross sections are also sensitive to the strange
valence quark distribution in the kaon, although one would need a significant
increase over the presently available kaon fluxes in order to extract this
quantity with sufficient accuracy.Comment: 9 pages plus 4 figures, on eps
