    We report a high-statistics measurement of the differential cross section of the process gamma gamma --> Ks Ks with the Belle detector. We study spectroscopy of light-quark resonances and charmonia and test QCD models using the data. We summarize our systematic measurements of different processes of gamma gamma --> meson pair production based on the parameterization of the cross...

    The process gamma pi --> pi pi, in the limit of vanishing photon and pion energies, is determined by the chiral anomaly. This reaction can be investigated experimentally using Primakoff reactions, as currently done at COMPASS. We derive a dispersive representation that allows to extract the chiral anomaly from cross-section measurements up to 1 GeV, where effects of the rho resonance are...
