Abstract
Results of high statistic two-photon collisions at Belle are presented. Only [Formula: see text] process is included in this report, here [Formula: see text] could be π+π-, K+K-, [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] or [Formula: see text]. Measurements of [Formula: see text] for charmonia resonance states are listed. A new χ′c2 candidate in [Formula: see text] has been identified as a spin-2 (helicity-2) object. Cross section and production angle distributions are measured and compared with various QCD calculations.
