We show that an angular analysis of B → V 1 V 2 decays yields numerous tests for new physics (NP) in the decay amplitudes. Many of these NP observables are nonzero even if the strong phase differences vanish. For certain observables, neither time-dependent measurements nor tagging is necessary. Should a signal for new physics be found, one can place a lower limit on the size of the NP parameters, as well as on their effect on the measurement of the phase of B 0 - 0 mixing.
