ISR physics at BABAR
Abstract
We present a review of BaBar results on e+e- annihilations into exclusive hadronic final states using the initial state radiation technique. Cross sections over the sqrts range from threshold to 4.5 GeV, with very small point-to-point systematic errors, are presented for the 3pi, 2(pi+ pi-), 3(pi+ pi-), 2(pi+ pi-)2pi0, K+ K- pi+ pi-, 2(K+ K-) and p anti-p final states. The proton form factor and the ratio of its electric and magnetic components are also presented.
