Baryon spectroscopy is important to understand Quantum Chromodynamics at low energies. In this purpose, a series of π0 and η photoproduction experiments was carried out with an electro-magnetic calorimeter FOREST at Research Center for Electron Photon Science, Tohoku University. The incident tagged bremsstrahlung photon energy ranges from 550 to 1,150 MeV. The differential and total cross sections...
The total cross section has been measured for ω meson photoproduction on the proton for the center-of-mass energy $${\sqrt{s}}$$ ranging from 1.69 to 1.75 GeV. Including the subthreshold region of ω photoproduction, a set of about 40 data points has been obtained with a fine energy step of 1–2 MeV. The data set enables us to deduce the ω-N scattering length.
