nN Backward Scattering
nN backward scattering data above 5 GeV /c are analyzed in terms of the baryon Regge pole exchange and accompanying Regge cut due to the strong absorption. The fit of the cross sections is reasonable. The role of the cut turns out to be very important: (1) The extrapolated magnitude of the L10 residue at a 4 =! is significantly larger than that without the cut. Ll0 residue with or without the w...
متن کاملNN Scattering Problem
It is shown that chiral perturbation theory (in its original form by Wein-berg) can describe N N scattering with positive as well as negative effective range. Some issues connected with unnaturally large N N 1 S 0 scattering length are discussed. The chiral perturbation theory approach to the low-energy purely pionic processes [1] has been generalised for processes involving an arbitrary number...
متن کاملRenormalising Nn Scattering: Is Power Counting Powerless?
The renormalisation of NN scattering in theories with zero-range interactions is examined using a cut-off regularisation where the cut-off is taken to infinity, dimensional regularisation (DR) with minimal subtraction, and DR with powerdivergence subtraction. In the infinite cut-off limit power counting breaks down: terms of different orders in the potential contribute to the scattering amplitu...
متن کاملRenormalization of NN scattering : contact potential
The renormalization of the T -matrix for NN scattering with a contact potential is reexamined in a nonperturbative regime through rigorous nonperturbative solutions. Based on the underlying theory, it is shown that the ultraviolet divergences in the nonperturbative solutions of the T -matrix should be subtracted through ”endogenous” counter terms, which in turn leads to a nontrivial prescriptio...
متن کاملRenormalizing the Schrödinger Equation for Nn Scattering
The renormalization of the Schrödinger equation with regular One Boson Exchange and singular chiral potentials including One and Two-Pion exchanges is analyzed within the context of NN scattering.
