ISR physics at BaBar

Druzhinin V.

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 √s range from threshold to 4.5 GeV, with very small point-to-point systematic errors, are presented for the 3π, 2(π+π-), 3(π+π-), 2(π+π-)2π0, K+K -π+π-, 2{K+K-) and pp final states. The proton form factor and the ratio of its electric and magnetic components are also presented. Copyright © 2006 by World Scientific Publishing Co. Pte. Ltd.
