K+/Ĉ+ Ratio vs Beam Energy
Ratio K+/Ĉ+ at yCM increases from 0.0271 at 2 AGeV to 0.202 at 10.7 AGeV.
Rescattering of hadrons contributes the enhancement of kaons within this energy range(sqrt(s)=2-6 AGeV) near production threshold.
The enhancement of (K/Ĉ)AA to (K/Ĉ)pp decrease steadily from 4 to 160 A GeV.
