We first review the standard model, the symmetries P, C, T, and CP, and the history of parity/signature tests. We proceed to obtain the decay correlation function I({theta}{sub 1}, {theta}{sub 2}, {phi}) and its integrated distributions for sequential decays X {yields} V{sub 1}V{sub 2}, where each V is a vector boson, and at least one of these vector bosons decay to final state pairs containing fermions of spin 1/2, specifically, leptons and quarks. We make fundamental symmetry determinations of the P or CP eigen-values of X from the decay modes JJ, {Upsilon}{Upsilon}, Z{sup 0}Z{sup 0} and W{sup +}W{sup {minus}}, {Phi}J, J{Upsilon}, {Phi}Z{sup 0}JZ{sup 0}, gZ{sup 0}, and gg, where g = gluon jet. This includes tests to distinguish between a spin 0 technipion and an elementary Higgs boson. These symmetry determinations require an accurate measurement of the coefficient of cos2{phi} in the azimuthal distribution for decay modes {Phi}J, JJ, Y Y, {Phi}Z{sup 0}, JZ{sup 0}, Z{sup 0}Z{sup 0}, W{sup +}W{sup {minus}} where the vector bosons other than {Phi} decay into l{sub A}l{sub B} and/or q{sub Z}q{sub B}. Simple tests for CP or P violation by sequential decays are given next.
