  In this article we introduce a family of valuative invariants defined in
terms of the $p$-th moment of the expected vanishing order. These invariants
lie between $\alpha$ and $\delta$-invariants. They vary continuously in the big
cone and semi-continuously in families. Most importantly, they can detect the
K-stability of Fano varieties, which generalizes the $\alpha$ and
$\delta$-criterions in the literature. They are also related to the
$d_p$-geometry of maximal geodesic rays.
