Abstract：In this talk we will present a solution of a longstanding open problem: Any stable free boundary CMC hypersurfaces in a ball are umbilic.

One of crucial ideas is a new weighted Minkowski identity for free boundary hypersurfaces. Our proof works also for capillary hypersurfaces in a ball in a space form. 

This is a joint work with Chao Xia (Xiamen University).
