Quantum Solitons Lead to Yukawa Coupling
Fermin Aldabe
Abstract
Recently, it was shown that zero modes in semiclassical soliton models do not lead to Yukawa couplings. We show that taking into account the contributions of the quantum soliton into the renormalization scheme, which cannot be done in semiclassical treatments, leads to a Yukawa coupling. A similar analysis should be possible for the Skyrmion, renewing the hope, that this model will lead to a correct description of hadron physics.
