Abstract

Antiproton production cross sections have been measured in minimum bias p+Be, p+Al, p+Cu, and p+Au collisions at 14.6 GeV/c with the E-802 spectrometer at the Brookhaven Alternating Gradient Synchrotron. The antiproton multiplicity at laboratory rapidities 1.0 to 1.6 shows almost no dependence upon the target mass. The p̄ production for p+Be is somewhat lower than an estimation based upon 19-24 GeV/c p+p data. In this rapidity interval the antiproton yield scales by a factor of 28±6 from p+Au to central Si+Au collisions.
