    "abstract": "The pion-nucleon scattering amplitudes are calculated in tree approximation\nwith the use of the extended linear sigma model (ELSM) as well as heavy baryon\nchiral perturbation theory (HB$\\chi$PT), and the non-relativistic forms of the\nELSM results are compared with those of HB$\\chi$PT. We find that the amplitudes\nobtained in ELSM do not agree with those derived from the more fundamental\neffective approach, HB$\\chi$PT.",
