74 The orbital angular momenta of the vector (spin 1) mesons, J/ and 0, produced in the
75 decay of the pseudoscalar (spin 0) B meson, are used to distinguish the CP-even S- and D-
76 wave final states from the CP-odd P-wave final state. We measure the decay angles BT, OT,
77 and 'T, defined in Ref. [9], in the transversity basis [16]. The transverse linear polarization
78 amplitudes at t = 0, Al and A, correspond to CP even and CP odd final states, respectively.
79 The longitudinal polarization amplitude AO corresponds to a CP even final state. The
so polarization amplitudes are required to satisfy the condition IA012 + A 2 + A12 = 1.
81 In order to separate the time development of the B meson from that of the B meson,
82 we identify the flavor of the B or B meson at the time of production by means of flavor
83 tagging. Two independent types of flavor tags are used, each exploiting specific features of
84 the production of b quarks at the Tevatron, where they are mostly produced as bb pairs. The
85 first type of flavor tag infers the production flavor of the B or B meson from the decay
86 products of the b hadron produced by the other b quark in the event. This is known as4
