Abstract

Photoproduction of the ? meson on the proton has been experimentally studied near the threshold. The total cross sections are determined at incident energies ranging from 1.09 to 1.15 GeV. The 1/2 and 3/2 spin-averaged scattering length a?p and effective range r?p between the ? meson and proton are estimated from the shape of the total cross section as a function of the incident photon energy: a?p=(-0.97±0.16)+ i (0.07±0.15) fm and r?p=(+2.78±0.61)+ i (-0.01±0.48) fm, which suggests a repulsive force. The real and imaginary parts for a?p and r?p are determined separately for the first time. The details of the analysis and discussions are described in Ref. [1].
