Simulation of Proton-proton Elastic Scattering at 3.2 GeV/c

3.2 GeV/c的质子-质子弹性散射模拟研究

The anti-proton annihilation at darmstadt(PANDA)will be a key experiment at the Facility for antiproton and Ion Research(FAIR).One of its main goals is to measure absolute cross section with precision better than 5%.In order to calibrate the PANDA luminosity,the key experiment for Panda luminosity calibartion(KOALA),which is to measure the anti-proton proton elastic scattering,will be carried out at the very beginning of the full run of PANDA.The total cross section(σtot),the ratio of the real to imaginary part of the scattering amplitude(ρ)。
