To facilitate exploiting the symmetry of (HF)3 we propose using local polar and azimuthal angles to specify the orientation of the HF units with respect to the frame of the trimer. We present and discuss the derivation of a kinetic energy operator in local polar and azimuthal angles and Pekeris–Jacobi coordinates. PACS No.: 31.15-P

The matrix element of the kinetic energy operator between B meson states is computed by means of a QCD relativistic potential model, with the result: [Formula: see text]. A comparison with the outcome of other theoretical approaches and a discussion of the phenomenological implications of this result are carried out.
