0 ... 0 1, (Q, Qi form an additive system of quantities), if [Q, P] = 0 (superselection rule), and if the reduced density matrix pi is obtained from the density matrix P by tracing out over the j-spaces, j -f i, then [qi , pi] = 0. This shows that a superselection rule for an additive quantity propa

We reinvestigate Bargmann's superselection rule for the overall mass of n particles in ordinary quantum mechanics with Galilei invariant interaction potential. We point out that in order for mass to define a superselection rule it should be considered as a dynamical variable. We present a minimal ex
