Proton–proton elastic scattering at 3.2 GeV/c is simulated for the newly constructed KOALA recoil detector. Theintegrated luminosity (𝐿), total cross section (𝜎𝑡𝑜𝑡), slope parameter (𝑏) and ratio of the real to imaginary part ofthe elastic scattering amplitude (𝜌) are extracted from the spectrum of the squared 4-momentum transfer, andtheir corresponding systematic errors are evaluated to be 5.40%, 1.79%, 1.80% and 0.0200, respectively. Basedon the simulation results, the precision of the luminosity is estimated to be better than 4%. It indicates thatthe KOALA recoil detector is a good candidate to determine 𝜎𝑡𝑜𝑡, 𝑏 and𝜌 with high precision and thus can beimplemented for the PANDA luminosity calibration. |
