Using data collected with the LHCb detector in proton-proton collisions at a centre-of-mass energy of 7 TeV, the hadronic decay inline image is observed. This CP eigenstate mode could be used to measure mixing-induced CP violation in the inline image system. Using a fit to the pi super(+) pi super(-) mass spectrum with interfering resonances gives inline image. In the interval +/-90 MeV around 980 MeV, corresponding to approximately two full f sub(0 widths we also find inline image, where in both cases the uncertainties are statistical and systematic, respectively.)
