Constructor & Destructor Documentation

CbmFastDecayer() [1/3]

CbmFastDecayer::CbmFastDecayer

(

)

Default constructor without arguments should not be used.

CbmFastDecayer() [2/3]

CbmFastDecayer::CbmFastDecayer	(	const char *	fileName,
		TString	particle )

Standard constructor.

Parameters

fileName

The input file name

ReadEvent()

Bool_t CbmFastDecayer::ReadEvent

(

FairPrimaryGenerator *

primGen

)

Reads on event from the input file and pushes the tracks onto the stack. Abstract method in base class.

Parameters

pStack	pointer to the stack
ver	not used

allow tracking of decay products

selection for geant and decay pdgs

select certain particles for decay

check for dalitz pi0, gamma, etc.

TODO: check

create lorentz vector

decay

select certain particles for decay

mother origin

only debug

NOTE: the first decay generation points to the generated particles (by e.g. UrQMD), further generations (cascade daughters) have jpa indices > 0 and need to point to the correct previously added mother (not grandmother) -> (i-jpa)

position and momentum of daughters

Give track to PrimaryGenerator NOTE: parent index need to be reduced by the stack size, because the index is shifted by this number in FairPrimaryGenerator::AddTrack!

deny tracking of decay products
