Solving integral equations in $$\eta \rightarrow 3\pi $$ η→3π

Abstract A dispersive analysis of $$\eta \rightarrow 3\pi $$ η→3π decays has been performed in the past by many authors. The numerical analysis of the pertinent integral equations is hampered by two technical difficulties: (i) The angular averages of the amplitudes need to be performed along a compl...
