From Skyrmions to NN phaseshifts

Abstract

We study the $NN$ phaseshifts in a Hamiltonian obtained from quantization of the collective modes in the Skyrme model. We show that a combination of an adiabatic and diabatic approximation gives a good $NN$ force, with sufficient attraction to produce a bound deuteron. The description of the repulsive core appears to be the main cause for the remaining discrepancies between the Skyrme model force and phenomenology. Finally we discuss the possibility of finding non-strange dibaryon resonances in the $J^{\pi }=3^{+}$ channel.
