Abstract (data abstract)
KEK-KEKB asymmetric collider. Measurement of the cross section for K+ K- production in two photon interactions produced in the collisions of 8 GeV electrons with 3.5 GeV positrons. The data were collected between 1999 and April 2002 corresponding to an integrated luminosity of 67 fb-1. The data are a combination of on and off resource data, the latter being taken at 60 MeV below the upsilon (4S) resonance at 10.58 GeV. Numerical values of figure 4 supplied by S. Uehara.
