ALICE-o2 AddTrack with mother/daughter indices

add track

add event vertex to track vertex

check if particle to be tracked exists in PDG database

set all other parameters required by PushTrack

if it is a K0/antiK0 to be tracked, convert it into K0s/K0L.

NOTE: we could think of pushing the K0/antiK0 without tracking first and then push she K0s/K0L for tracking. In this way we would properly keep track of this conversion, but there is the risk of messing up with the indices, so this is not done for the time being.

compute particle energy if negative

add track to stack

◆ GenerateEvent()

Bool_t o2::eventgen::PrimaryGenerator::GenerateEvent ( FairGenericStack * pStack )

override

Public method GenerateEvent To be called at the beginning of each event from FairMCApplication. Generates an event vertex and calls the ReadEvent methods from the registered generators.

Parameters

pStack The particle stack

Returns: kTRUE if successful, kFALSE if not

generate event

normal generation if no embedding

this is for embedding

setup interaction vertex

notify event generators

generate event

add embedding info to event header

increment embedding counter
