class AliOmegaDalitz: public TVirtualMCDecayer


 Generate lepton-pair mass distributions for Dalitz decays according
 to the Kroll-Wada parametrization: N. Kroll, W. Wada: Phys. Rev 98(1955)1355

 For the electromagnetic form factor the parameterization from
 Lepton-G is used: L.G. Landsberg et al.: Phys. Rep. 128(1985)301
