BaBar Results on Hadronic Cross Sections with Initial State Radiation

2008

In this paper we present recent results of the BaBar experiment at the B-factory PEP-II in the field of hadronic cross section measurements. At PEP-II, which is designed for a fixed center-of-mass energy around the ϒ(4S) resonance, the hadronic cross section is measured using events with Initial State Radiation (ISR), which allows the cover the entire energy range below 4 GeV in one single experiments. Results for exclusive finals states with 3, 4 and 5 hadrons, as well as measurements of hyperon form factors are shown.
