✦ Synopsis

We present a new chiral expansion scheme for the nucleon-nucleon scattering amplitude which preserves unitarity exactly. Our effective field theory builds on the power counting rules for 2-nucleon reducible diagrams. We evaluate the leading order terms of the isospin one scattering amplitude and elaborate in detail on the 1 S 0 phase shift. Our chiral description of the 1 S 0 -phase shift does compete in quality with modern phenomenological nucleon-nucleon potentials. We describe elastic and inelastic scattering quantitatively up to laboratory energies of E lab 600 MeV.

We have established a new convergent scheme to treat analytically nucleon-nucleon interactions from a chiral effective field theory. The Kaplan-Savage-Wise (KSW) amplitudes are resummed to fulfill the unitarity or right-hand cut to all orders below pion production threshold. This is achieved by matc
