In the context of the observable R, we also compare our model of 2-particle decoherence with the case where the analogous dissipative term can use formula (2.5) to obtain a completely positive dissipative term in the time evolution the case of the 2-particle B0B̄0 state, generated by the decay of the Υ(4S) resonance (for state which we assume to evolve exactly according to QM, with the time evolution given by For t > t', it is denoted by ρr(t'; t) and follows the 1-particle time evolution. with the case where we have the analogous time evolution (2.3) at the 1-particle level [12,13]. term which we have added to the quantum-mechanical time evolution could be an effective	./cache/work_pzwnbpkqjnczncdbdyjlkoomsi.pdf	./txt/work_pzwnbpkqjnczncdbdyjlkoomsi.txt
