Abstract

We measured the cross section for the γ γ → π ⁺π ^- process in the pion pair invariant mass range of 1.0--1.5, GeV/c² with the VENUS detector at TRISTAN. The γ γ decay width of the f₂(1270) resonance was obtained by using Vermaseren's model and a partial wave analysis. The results from both analyses were in good agreement. The partial wave analysis indicated the presence of a J=0 component around at 1.2, GeV/c² with a resonance-like structure.
