Unusual initial and final state effects in quantum chromodynamics. Annual progress report, July 15, 1991--December 20, 1991
We have constructed a number of fundamental tests which can be used to probe discrete symmetries, and their possible violations, in the required ``new physics`` beyond the standard model. On-going experiments with unpolarized e{sup {minus}}e{sup +} collisions contain many events for the production-decay sequence e{sup {minus}}e{sup +} {yields} Z{degrees}, {gamma}* {yields} {tau}{sup {minus}}{tau}{sup +} {yields} (A{sup {minus}X}) (B{sup +}X). From the beam referenced spin-correlation function for this sequence, the photon and Z{degrees} boson couplings of the tau lepton can be completely measured. There are four distinct tests for CP/T violation in Z{degrees} {yields} {tau}{sup {minus}}{tau}{sup +}, and in {gamma}* {yields} {tau}{sup {minus}}{tau}{sup +}. The Lorentz structure of the associated helicity amplitudes is very simple. In other research programs, we are (1) continuing to investigate our proposal that partons be identified with nearly degenerate, coherent quark-gluon ``jet`` states, and are (2) investigating the novel consequences of q-analogue quantization of quantum fields, and of a completeness relation for the q-analogue coherent states.
