Phys. Rev. Lett. 84, 5049–5052 (2000)Universality in the Nuclear Dependence Coefficient α(qT)Received 24 November 1999; published in the issue dated 29 May 2000 We derive the nuclear dependence coefficient α(qT) for Drell-Yan and J/ψ production. We show that at small qT, α(qT) is given by a universal functional form: α(qT) = a+bqT2, and the parameters a and b are completely determined by either perturbatively calculable or independently measurable quantities. This universal functional form α(qT) is insensitive to A, and is consistent with existing data. © 2000 The American Physical Society URL:
