Second-order Eikonal Model Analysis for the π±+¹²C Elastic Scattering at p = 995 MeV/c

Second-order Eikonal Model Analysis for the π±+¹²C Elastic Scattering at p = 995 MeV/c

We present the closed expression for the eikonal phase shifts, including up to the second-order corrections, which has been applied to elastic scatterings of the π⁺+¹²C and the π⁻+¹²C systems at p = 995 MeV/c. The calculated angular distributions, taking into account the first- and the second-order eikonal phase shifts, show extraordinarily good agreement with the observed data. We also investigate how angular distributions can be influenced by the effective potentials.
