Production of 3π0 in pp reactions above the η production threshold and the quadratic slope parameter α

Description

The CELSIUS-WASA setup has been used to measure the production of 3π0 in pp interactions at Tp = 1360 and 1450 MeV. A cross section for the prompt pp → pp3π0 and resonant pp → pp (η → 3π0) reaction channel is determined. The efficiency corrected Dalitz plot and density distribution for the η → 3π0 decay are shown, together with a fit of the quadratic slope parameter α. Our preliminary result for α is -0.027 ± 0.009 (stat) ± 0.01 (syst) (Authors)
