Abstract
We overview baryons in a string theoretical holographic QCD. In the large Nc limit, the baryon can be viewed in two different ways. The first is a holographic lift of Skyrmion, except that not only pions but also an infinite number of spin 1 mesons are used to construct the solitonic baryon. This approach has been pursued to give an infinitely predictive model of meson–baryon dynamics. After a brief review, we comment on the alternative picture where the baryon is viewed as wrapped D-branes, which leads to a quantum mechanical description involving matrices. The two approaches give surprisingly similar answers for some quantities, such as hadronic size of baryons and repulsive cores, even though they represent two very different approximations.
