Observables in the decays of B to two vector mesons - art. no. 074031

In general there are nine observables in the decay of a B meson to two vect or mesons defined in terms of polarization correlations of these mesons. On ly six of these can be detected via the subsequent decay angular distributi ons because of parity conservation in those decays. The remaining three req uire the measurement of the spin polarization of one of the decay products.
