• We describe a measurement of the time-integrated luminosity of the data collected by the BABAR experiment at the PEP-II asymmetric-energy e^+e^- collider at the ϒ(4S), ϒ(3S), and ϒ(2S) resonances and in a continuum region below each resonance. We measure the time-integrated luminosity by counting e^+e^-→e^+e^- and (for the ϒ(4S) only) e^+e^-→μ^+μ^- candidate events, allowing additional photons in the final state. We use data-corrected simulation to determine the cross-sections and… CONTINUE READING
