Dear @NicoleBastid , thanks a lot for the work! It looks fine for me. I just have a minor question, as mentioned in the review. I am not sure if you want to further constrain the generator triggered on the desired hadron. But if not, I think we can just merge it. And the async-labe should be added only for the developments backported to the older tags.

Hi @NicoleBastid , do you have any expected numbers of these muons and those in acceptance?

### The external generator derives from GeneratorPythia8.

I see you have the debug output about the nMuonsInAcceptance in the test macro. As you may know, it is also possible to constrain the desired hadron within the given rapidity range in the GeneratorPythia8GapTriggeredBeauty. If that's what you want, one could also trigger based on the hadronPdgList. But I am not sure if this has been used before.
