  • We conjecture that the ``nilpotent points" of Calogero-Moser space for reflection groups are parametrised naturally by the two-sided cells of the group with unequal parameters. The nilpotent points correspond to blocks of restricted Cherednik algebras and we describe these blocks in the case $G = \mu_{\ell}\wr \mathfrak{S}_n$ and show that in type $B$ our description produces an existing conjectural description of two-sided cells.
