Abstract

Antiproton production cross sections have been measured for minimum bias and central Si+Al and Si+Au collisions at 14.6 A GeV c. The data presented cover the range of transverse momentum from 0.3 to 1.2 GeV c and lab rapidities from 1.1 to 1.7 units. The relative p π^- and p K^- yields are found to be the smallest for the heaviest system measured, central Si+Au collisions. For these collisions, the p π^- ratio, determined from integrated yields for 1.1≤y≤1.7, is (0.84±0.07)×10^-3. In the same rapidity interval, the average antiproton inverse m⊥ slope is 141±14 MeV for central Si+Al and central Si+Au collisions.

N2 - Antiproton production cross sections have been measured for minimum bias and central Si+Al and Si+Au collisions at 14.6 A GeV c. The data presented cover the range of transverse momentum from 0.3 to 1.2 GeV c and lab rapidities from 1.1 to 1.7 units. The relative p π- and p K- yields are found to be the smallest for the heaviest system measured, central Si+Au collisions. For these collisions, the p π- ratio, determined from integrated yields for 1.1≤y≤1.7, is (0.84±0.07)×10-3. In the same rapidity interval, the average antiproton inverse m⊥ slope is 141±14 MeV for central Si+Al and central Si+Au collisions.
