Baryon as dyonic instanton
arXiv:1206.4515 · doi:10.1103/PhysRevD.86.126005
Abstract
We discuss the baryon in the holographic QCD framework and focus on the role of the bifundamental scalar field, realizing chiral symmetry breaking. We suggest the interpretation of a baryon as a dyonic instanton within the Atiyah-Manton-like approach for the flavor gauge group in the peculiar cylindrical ansatz in five-dimensional theory. Our approach provides the new mechanism of the stabilization of the baryon size.
