Dear Ralph et al.,

regarding vertex fitters, tree fitters and 4C fitters: which fitters assume outgoing tracks being helices? If I understood correctly:

1) The vertex fit assumes two outgoing helix trajectories
2) The tree fitter should treat both neutral and charged tracks but one needs to fix the masses of the intermediate states
3) The 4C fit assumes helices coming from the interaction point and should therefore not be used in any hyperon channel

Is this correct?

Kindest regards,
