Hi Lia,

in principle the charge can change in the fit. q/p, i.e. the signed curvature is a variable of the fit. It could be possible in some cases (very few hits close to each other, very high momenta, ....) that the sign of q/p can be wrongly reconstructed. q/p has a finite resolution. The track topology of these 3% of tracks must be special...

Cheers, Christian
