In a phiJ, JJ, or JUPSILON decay channel sin 2phi and/or sin phi terms in the azimuthal distribution would imply that P and CP separately are violated. Similarly in a phiZ, JZ, ZZ, or W W decay channel sin 2phi terms would imply that CP is violated. For these latter modes there are several distinct and el signatures for CP violation. Analogous signatures for expected P violation occur in a charged phiW , JW , or ZW decay channel. Stronger tests for violations occur when the two vector bosons are identical and the X has odd spin because for J = 1 (>1) there are only two (three) independent amplitudes. For X of spin 0 many signatures and consistency checks are tabulated for (i) the violation of both P invariance and CP invariance in a phirho, phiphi, K/sup asterisk+/K/sup asterisk-/, phiJ, JJ, or JUPSILON decay channel, for (ii) the violation of CP invariance in a phiZ, JZ, ZZ, or W W decay channel, and for (iii) the expected violation of P invariance in a charged phiW , JW , or ZW decay channel.
