Abstract [en]

One of the objectives of the physics programme of the WASA-at-COSY facility is to study the isospin violating eta hadronic decays into pi(+)pi(-)pi(0) systems driven by the term of QCD Lagrangian which depends on the d and u quark mass difference. These studies can be made in terms of the Dalitz plot parameters describing the density population which is proportional to the square of the amplitude vertical bar A(x,y)vertical bar(2). This contribution describes the current status of the analysis of the eta -> pi(+)pi(-)pi(0) decay in the pd ->(3) He eta and as well in the pp -> pp eta reaction with WASA-at-COSY.
