Hi Ingo,

Thanks very much for your response.

Because Sigma13850->Lambda dilepton is also Dalitz decays which is very like Delta->N diLepton already defined in PDalitzDecay.cc, I add the Sigma13850 Dalitz decay in PDalitzDecay.cc,

as well I add this sentence accordingly in the simulation code:
 PReaction *my_reaction = new PReaction("_P1 = 11.0","e-","p","e- Delta1910+ [Sigma13850 [dilepton [e+ e-] Lambda] K+]","YtosigmaK",0,0,0,0);


and the modified PDalitzDecay.cc/h and simulation code tmp_YtoLambdaee.C are shown in the attachment.


Here new problem arises,

the output when I finished running the tmp_YtoLambdaee.C and quit the root, the root bursts out some errors as follows,

root [0]

Does it means that the memory used in this simulation process exceeds the limit? if so, how to solve it?
