    Let BB be a simple CM abelian variety over a CM field EE, pp a rational prime. Suppose that BB has potentially ordinary reduction above pp and is self-dual with root number −1-1. Under some further conditions, we prove the generic non-vanishing of (cyclotomic) pp-adic heights on BB along anticyclotomic Zp\Z_{p}-extensions of EE. This provides evidence towards Schneider's conjecture on the non-vanishing of pp-adic heights. For CM elliptic curves over \Q, the result was previously known as a consequence of work of Bertrand, Gross--Zagier and Rohrlich in the 1980s. Our proof is based on non-vanishing results for Katz pp-adic LL-functions and a Gross--Zagier formula relating the latter to families of rational points on BB.Comment: Ann. Inst. Fourier, to appea
