Abstract: We specify recursive equations that could be used to generate a lowest orderparton shower for hard scattering in hadron-hadron collisions. The formalism isbased on the factorization soft and collinear interactions from relativelyharder interactions in QCD amplitudes. It incorporates quantum interferencebetween different amplitudes in those cases in which the interference diagramshave leading soft or collinear singularities. It incorporates the color andspin information carried by partons emerging from a hard interaction. Onemotivation for this work is to have a method that can naturally cooperate withnext-to-leading order calculations.
