摘要：

Positive pion and kaon production from Au + An reactions have been measured as a function of beam energy over the range 2.0-10.7 AGeV. Both the kaon and the pion production cross-sections at mid-rapidity are observed to increase steadily with beam kinetic energy. The ratio of K+ to pi(+) mid-rapidity yields increases from 0.0271 +/- 0.0015 +/- 0.0014 at 2.0 AGeV to 0.202 +/- 0.005 +/- 0.010 at 10.7 AGeV and is larger than the K+/pi(+) ratio From p + p reactions over the same beam energy region. There is no indication of a strong onset of any neu production mechanism in heavy-ion reactions in this energy range beyond rescattering of hadrons. (C) 2000 Published by Elsevier Science B.V.
