Dear experts,
I am trying to use RooFit generator to generate events on Dalitz plot.
As can be seen the plot attached.
There is a strange empty region near the edge which is not expected.
Btw looking at the output of the function value, the values in the empty place are similar to that of the other places.
By changing the options
RooAbsPdf::defaultGeneratorConfig()->getConfigSection(“RooFoamGenerator”).setRealValue(“nSample”,1e3);
RooAbsPdf::defaultGeneratorConfig()->getConfigSection(“RooFoamGenerator”).setRealValue(“nCell2D”,1e3);
The empty place moves from one place to another, but always exist.
Does anyone know what I should do in this case?
Many thanks
Wenbin
