Abstract

We describe the method of measuring the integrated luminosity of the e+e? collider DA?NE, the Frascati ?-factory. The measurement is done with the KLOE detector selecting large angle Bhabha scattering events and normalizing them to the effective cross section. The e+e? ?e+e?(?) cross section is calculated using different event generators which account for the O(?) radiative initial and final state corrections, and the ? resonance contribution. The accuracy of the measurement is 0.6%, where 0.3% comes from systematic errors related to the event counting and 0.5% from theoretical evaluations of the cross section.
