Abstract：
In this paper we investigate and obtain the large momentum behavior of the B.Swave function of the 1⁺⁺ meson and the electromagnetic transitional form factor F_{A_1π}.(q²) using the operator product expansion and the renormalization group approach.The possible experimental tests are also discussed succinctly.
