Brane-induced Skyrmions: Baryons in Holographic QCD
Kanabu Nawa, Hideo Suganuma, Toru Kojo
Abstract
We study baryons in holographic QCD with D4/D8/D8 multi D brane system. In holographic QCD, the baryon appears as a topologically non-trivial chiral soliton in a four-dimensional effective theory of mesons, which is called `Brane-induced Skyrmion'. We derive and calculate the Euler-Lagrange equation for the hedgehog configuration with chiral profile F(r) and ρ-meson profile G(r), and obtain the soliton solution of the holographic QCD.
