Decay Chain Syntax

Asked by Jasmina

Hello,

I am working with the following process p p > z z j j , ( z > l+ l- ) /h . Using this syntax, both z can decay in the same final state. Is there a way to generate a process where the z particles decay in different final states, namely one z in a e+e- state and the other z in mu+mu- ? Also I noticed that whether I use " /h " or not, it makes no difference in the number of diagrams that are generated for the process. This was not what I expected. Is there a reason for this? Thank you in advance.

Greetings,
Jasmina

Dear Jasmine,

I guess that the syntax that you are looking for is "generate p p > z z j j / h, z > e+ e- , z > mu+ mu-

Cheers,

Olivier
