A factorization theorem for P-wave quarkonium production, recently derived by Bodwin, Braaten, Yuan and Lepage, is applied to Υ→ χcJ + X, where χcJ labels the 3 PJ charmonium states. The widths for χcJ production through color-singlet P-wave and color-octet S-wave c c subprocesses are computed each to leading order in αs. Experimental data on Υ→ J / ψ+ X is used to obtain an upper bound on a nonperturbative parameter (related to the probability for color-octet S-wave c c hadronization into P-wave charmonium) that enters into the factorization theorem.
