It is unknown whether very general cubic threefolds have an (integral Chow-theoretic) decomposition of the diagonal, or whether they are stably rational or not. As a first step towards making progress on these questions, we compute the (saturated numerical) prelog Chow group of the self-product of a certain degeneration of cubic threefolds.

Matrix factorizations and intermediate Jacobians of cubic threefolds
Results due to Druel and Beauville show that the blowup of the intermediate Jacobian of a smooth cubic threefold X in the Fano surface of lines can be identified with a moduli space of semistable
The diagonal of quartic fivefolds
We show that a very general quartic hypersurface in P over a field of characteristic different from 2 does not admit a decomposition of the diagonal, hence is not retract rational. This generalizes a

For a simple normal crossing variety X, we introduce the concepts of prelog Chow ring, saturated prelog Chow group, as well as their counterparts for numerical equivalence. Thinking of X as the

We classify all positive integers n and r such that (stably) non-rational complex r-fold quadric bundles over rational n-folds exist. We show in particular that for any n and r, a wide class of

The motivic nearby fiber and degeneration of stable rationality
We prove that stable rationality specializes in regular families whose fibers are integral and have at most ordinary double points as singularities. Our proof is based on motivic specialization
