I think sign is just a short equal to 1 or -1 this is ok but you could also consider track.p() * track.sign() as it is not the charge, it is really the sign

if ((track.beta() * track.beta()) < 1.) {
gamma = 1.f / TMath::Sqrt(1.f - (track.beta() * track.beta()));
massTOF = track.p() / TMath::Sqrt(gamma * gamma - 1.f);
