// This is a concrete class based on G4VAuxiliaryTrackInformation. It is

// that have this track information and is deleted only when all tracks

// have been tracked.

// Class Description:
|

// A clipboard for communicating between quantum entangled photons
|

// from e+ annihilation. Applies only to the two-gamma decay from the
|

// JP=0- state of e+e-, para-positronium. (This is the dominant process
|
||||
// in materials such as human tissue, since the ortho-positronium JP=1-
|
||||
// state, initially more likely, is "picked off" by a near-by electron
|
||||
// and turned into para-positronium, because it has the much shorter
|
||||
// meanlife.)
|
||||
// Also applies to pi zero (JP=0-).
