We establish a bijection between d-simple-minded systems (d-SMSs) of (-d)-Calabi-Yau cluster category C-d (H) and silting objects of D-b(H) contained in D-<= 0 boolean AND D >= 1-d for hereditary algebra H of Dynkin type and d >= 1. We show that the number of d-SMSs in C-d (H) is the positive Fuss-Catalan number C-d(+)(W) of the corresponding Weyl group W, by applying this bijection and Buan-Reiten-Thomas' and Zhu's results on FominReading's generalized cluster complexes. Our results are based on a refined version of silting-t-structure correspondence.
