Exclusive hadronic cross sections measured via ISR from BABAR

Between 1999 and 2008 a data set of approximately 500 fb−1was recorded with the BABAR detector at the B-Factory PEP-II at SLAC (Stanford, USA), an electron-positron storage ring with fixed Center of Mass energy of 10.58 GeV. Using the technique of Initial State Radiation the energy range from threshold up to 4.5 GeV can be accessed. The measurement of the important process e+e−→π+π− and other channels will be presented.
