For the Drell-Yan procetaus, we have found a ''jet'' based factorization occurs when initial coherent states are used to avoid the higher twist, two-loop counter-examples to the Bloch-Nordsieck theorem in QCD. We have begun to analyze other examples to see whether this ''jet'' based factorization generalizes. An explicit anti-energy-ordering can be conveniently used to factorize a non-abelian Coulomb interaction operator out of the initial coherent state operator so as to proceed per the Kuhlish-Faddeev approach in QED. Secondly, we are completing analysis of a possible method of CP determination using the spin O decay H ..-->.. anti f/sub 1/f/sub 2/ where anti f/sub 1/f/sub 2/ are a pair of spin 1/2 fermions. For the tau/sup +/tau/sup -/ mode yielding ..mu../sup + -/e/sup -/, we are able to analytically obtain the full distribution I(E/sub ..mu../, E/sub e/, psi) in the H/sup 0/ rest frame where psi is the angle between the ..mu../sup +/ and e/sup -/ momenta. We are studying the ..gamma../sub CP/ dependence as a function of the H/sup 0/ mass ranges of empirical interest.
