Beilinson–Bloch conjecture on the Albanese kernel

Let KK be a number field and let Z/KZ/K be a smooth projective irreducible variety of dimension dd. Define the Albanese kernel by

T(Z):=Ker(CHd(Z)0Alb(Z)).T(Z):=\operatorname{Ker}\left(\mathrm{CH}^d(Z)_0\to\operatorname{Alb}(Z)\right).

Here CHd(Z)0\mathrm{CH}^d(Z)_0 is the group of homologically trivial zero-cycles and Alb(Z)\operatorname{Alb}(Z) is the Albanese variety. Beilinson–Bloch conjecture. The Albanese kernel T(Z)T(Z) is a finite group. This is a special case of the Beilinson–Bloch conjectures concerning zero-cycles on varieties over number fields; the supplied text does not state whether this case has been resolved.
