The axial-vector mesons a1(1260), b1(1235), f1(1285), h1(1170), h1(1380), and K1(1270) are dynamically generated in the unitized chiral perturbation theory. Such a picture has been tested extensively in the past few years. In this work, we calculate the interaction kernel up to O(p2) and study the impact on the dynamically generated axial-vector states. In anticipation of future lattice QCD simulations, we calculate the scattering lengths and the pole positions as functions of the pion mass, with the light-quark mass dependence of the kaon, the eta, and the vector mesons determined by the nf=2+1 lattice QCD simulations of the PACS-CS Collaboration.
