In the past year we have proposed a variation of the QCD parton model in which the partons are identified with nearly degenerate quark-gluon states. This relies only on the Kinoshita-Lee-Nauenberg theorem to cancel infrared singularities. Calculations at O(..cap alpha../sub s/) were then done for deep inelastic scattering for the nonsinglet structure functions and the nonsinglet operator matrix elements. In both quantities, the soft infrared singularities cancel and the collinear singularities cancel. Thus the proposal has been implemented. By the operator product expansion the associated coefficient function is obtained and it is the usual one. About a year ago we discovered that: (1) the phi phi parity test can be generalized to a CP test for distinguishing a neutral spin-O technipion from an elementary Higgs particle; and that (2) there are simple tests for possible violations of P, of the combination of C plus isospin, of both P and CP, and of both C and CP. We have now extended these generalizations to cover the V/sub 2/V/sub 2/ decay channels of more massive Higgs or techni bosons such as phi J, J UPSILON, phi Z/sub 0/, JZ/sub 0/, Z/sub 0/Z/sub 0/, and W/sup +/W/sup -/ where J/psi, UPSILON, 1/sup 2 -/ toponium, Z/sup 0/ and W/sup + -/ go into a lepton-antilepton pair, and also to gZ/sup 0/ and gg decay channels, g = gluon jet, which would be relevant to new jet-resonance physics. These new results demonstrate that modern colliders can make fundamental symmetry tests by analysis of sequential decays (without difficult, initial or final state, polarization experiments).
