A new determination of the πN coupling constantf 2

  • Published:
Zeitschrift für Physik A Hadrons and nuclei

Abstract

The coupling constantf 2 has been determined from forward dispersion relations for theπN helicity flip and no-flip amplitudes, using the recent information on total cross sections, phase shifts and charge exchange forward cross sections. The calculation gives also the values of the amplitudes and the first derivative at the crossing symmetry point.
