Dear all,

to complete the story, I have prepared
few plots for p+p at Ekin=1.25 GeV.

Figure bellow shows the mass dependent
branching ratio of Delta estimated by dividing
pp->pDelta+->pppi0 by pp->pDelta+->ppe+e-

The next point which was checked concerns the following issue:

Bellow you can find a figure which shows the
Delta+ mass distribution in channel pp->pD+->ppe+e-
for two versions of Pluto. Indeed, the Krivoruchenko
model was not enable in the Pluto versions < v5.38.2!

Finally, you can see the influence on invariant
e+e- mass spectrum:
