9. Notice that parametrizations of the B and B̄ decay amplitudes using the same weak and strong phases, as in Eqs. 1 2, only keep this form if the state kets |B and |B̄ are rephased with the same phase ξB. This type of change can be absorbed with a modification of any strong phase δ into δ′=δ+ξB. This rephasing freedom can be used to reduce the number of parameters on the right-hand-sides of Eqs. 1 2. The possibility of changing the two state vectors, |B and |B̄ with different phases brings some subtleties. Additional care must be taken with possible rephasings of the quark field operators that mediate the decays. These issues are explained in detail in.
