Probability of Color Rearrangement at Partonic Level in Hadronic W^+W^- Decays

Abstract

A strict method to calculate the color rearrangement probability at partonic level in hadronic $W^{+}{W}^{-}$ decays is proposed. The color effective Hamiltonian $H_c$ is constructed from invariant amplitude for the process $e^{+}{e}^{-}\to W^{+}{W}^{-}\to q_1{\bar{q}}_2{q}_3{\bar{q}}_4+ng$ (n=0, 1, 2, ...) and is used to calculate the cross sections of various color singlets and the color rearrangement probability. The true meaning of the color rearrangement is clarified and its difference from color interference is discussed.
