    "abstract": "A microscopic model for the $N\\bar N\\to\\pi\\pi$ process is presented in the\nmeson exchange framework, which in the pseudophysical region agrees with\navailable quasiempirical information. The scalar ($\\sigma$) and vector ($\\rho$)\npiece of correlated two--pion exchange in the pion--nucleon interaction is then\nderived via dispersion integrals over the unitarity cut. Inherent ambiguities\nin the method and implications for the description of pion--nucleon scattering\ndata are discussed.",
