英文摘要	We consider a holographic QCD model for light mesons beyond the leading order in the context of 5-dim gauged linear sigma model on the interval in the AdS(5) space. We include two dimension-6 operators in addition to the canonical bulk kinetic terms, and study chiral dynamics of pi, rho, a(1) and some of their KK modes. As novel features of dim-6 operators, we get non-vanishing Br(a(1) -> pi gamma), the electromagnetic form factor and the charge radius of a charged pion, which improve the leading order results significantly and agree well with the experimental results.
