| Abstract
| - Study of the η → π+π−π0 decay allows for precise tests of the C parity conservation, makes possible to set constraints on the u and d as well as s and d quark mass ratios and can be used for a verification of the predictions of the Chiral Perturbation Theory (ChPT). The WASA-at-COSY collaboration has accumulated the world largest numbers of η mesons produced in p − d and p − p collisions. This report includes preliminary results of the ongoing analysis of the η → π+π−π0 decay from p − p data which were collected during 8 weeks of the COSY beam time in 2010 in Forschungszentrum Jülich with more than 10 8η mesons produced.
