Abstract / Description of output

A precise measurement of the Dalitz plot parameter, alpha, for the eta -> 3 pi(0) decay is presented. The experiment was performed with the Crystal Ball and TAPS large-acceptance photon detectors at the tagged photon beam facility of the MAMI-B electron accelerator in Mainz. High statistics of 1.8.10(6) eta -> 3 pi(0) events were obtained, giving the result alpha = -0.032 +/- 0.002(stat) +/- 0.002(syst).
