Query: Chiral currents and static properties of nucleons in holographic QCD   We analyze static properties of nucleons in the two flavor holographic QCD
model of Sakai and Sugimoto described effectively by a five-dimensional U(2)
Yang-Mills theory with the Chern-Simons term on a curved background. The
baryons are represented in this model as a soliton, which at a time slice is
approximately the BPST instanton with a fixed size. First, we construct a
chiral current in four dimensions from the Noether current of local gauge
transformations which are non-vanishing on the boundaries of the extra
dimension. We examine this chiral current for nucleons with quantized
collective coordinates to compute their charge distribution, charge radii,
magnetic moments and axial vector coupling. Most of the results are better
close to the experimental values than in the Skyrme model. We discuss the
problems of our chiral current; non-uniqueness of the local gauge
transformation for defining the current, and its gauge-noninvariance.
