We construct (q;t)-Catalan polynomials and q-Fuss-Catalan polynomials for any irreducible complex reection group W. The two main ingredients in this construction are Rouquier's formulation of shift functors for the rational Cherednik algebras of W , and Opdam's analysis of permutations of the irreducible representations of W arising from the Knizhnik-Zamolodchikov connection. In the special case of well-generated groups, this conrms conjectures of Bessis and Reiner.
