We compare our approach with other related works, and examine a coherent state description of pions in the baryon structure. Our solution suggests a kind of nucleon resonance due to the topological change of pion field without the usual quark excitation.14 pages, 1 figure, Revtex4, submitted to a journalHigh Energy Physics - PhenomenologyNuclear TheoryQuasi-coherent state of pions in the nucleontext
