High-statistics study of KFormula pair production in two-photon collisions
High-statistics study of KFormula pair production in two-photon collisions
We report a high-statistics measurement of the differential cross section of the process |$\gamma \gamma \to K^0_S K^0_S$| in the range |$1.05\,{\mathrm {GeV}} \leq W \leq 4.00$| 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 …
