K^±p elastic scattering in the QCD inspired eikonalized model

Abstract

Based on our previous study of the QCD inspired eikonalized model for describing vector meson photoproduction, pp, and \overline{p}p elastic scattering at high energies, we apply the mode to high energy K^±p elastic scattering. The total cross section σ_tot(s), differential cross section dσ/dt, the ratio of the real part to imaginary part of the forward scattering amplitude ρ(s), and nuclear slope parameter function β(s) are calculated in the model. Our results show that the theoretical prediction for σ_tot(s) is in a good agreement with the experimental data within error bars of the data. For the other theoretical predictions there are no data to test the predictive power of the model. We need the corresponding experimental data to examinate the validity of our QCD inspired eikonalized model. However, our calculations clearly show that the Odderon exchange in the process makes a significant contribution to the observable of ρ(s) and β(s). Therefore, we may conclude that there is a good opportunity to find the QCD Odderon in the K^±p elastic scattering at high energies.
