Title: High-statistics study of $$K^0_S$$ pair production in two-photon collisions

Abstract

We report a high-statistics measurement of the differential cross section of the process $$γγ → K^0_S K^0_S$$ in the range 1.05 GeV $≤ W ≤$ 4.00 GeV, where $$W$$ is the center-of-mass energy of the colliding photons, using 972 fb-1 of data collected with the Belle detector at the $KEKB$ asymmetric-energy $e^+ e^-$ collider operated at and near the $$Υ$$-resonance region. The differential cross section is fitted by parameterized S-, D0-, D2-, G0- and G2-wave amplitudes. In the D2 wave, the $$f_2$$(1270), $$a_2$$(1320) and $$f^\prime_2$$(1525) are dominant and a resonance, the $$f_2$$(2200), is also present. The $$f_0$$(1710) and possibly the $$f_0$$(2500) are seen in the $$S$$ wave. The mass, total width and product of the two-photon partial decay width and decay branching fraction to the $$K\overline{K}$$ state $$Γ_{γγ}(ΒK\overline{K})$$ are extracted for the $$f^\prime_2$$(1525), $$f_0$$(1710), $$f_2$$(2200) and $$f_0$$(2500). The destructive interference between the $$f_2$$(1270) and $$a_2$$(1320) is confirmed by measuring their relative phase. The parameters of the charmonium states $$Χ_{c0}$$ and $$Χ_{c2}$$ are updated. Possible contributions from the $$Χ_{c0}(2P)$$ and $$Χ_{c2}(2P)$$ states are discussed. A new upper limit for the branching fraction of the $P-$ and $CP-$violating decay channel $$η_c → K^0_S K^0_S$$ is reported. The detailed behavior of the cross section is updated and compared with $QCD$-based calculations.
