Abstract

Small oscillations of the static Skyrme soliton are considered. It is found that the Skyrme soliton is stable against small oscillations and there is no bound state. The meson-soliton scattering phase shifts are calculated. A resonance is found at 250-300 MeV above the nucleon, which is only halfway from the Roper resonance N*(1440). Small oscillations are also considered for spinning Skyrme solitons. The results are similar. Some implications and difficulties associated with spinning solitons are discussed.
