Hello Aleksandr,

Your last assumption is correct. The Vertex Fitters work only on charged particles.

In your special case the vertex fit would not help you much. Both the psi2s and the j/psi decay at the interaction point (0,0,0) if you have not set a smeared interaction region durig simulations. The four momenta are already calculated at (0,0,0) by default.

Cheers
Ralf
