Predictions of quaternionic quantum mechanics for CP nonconservation in the B and D meson systems

We apply the quaternionic quantum mechanics model for CP nonconservation, previously developed by Adler for K mesons, to heavy-flavor systems. We show that unlike superweak models, it can accommodate anomalously large D0-D-bar 0 mixing. On the other hand, in common with superweak models, the quaternionic model predicts zero partial-decay-rate asymmetries for decays of charged B and D mesons, and predicts final-state-independent partial-decay-rate asymmetries for the decays of neutral B and D mesons into CP eigenstates
