Beilinson's Albanese isomorphism conjecture for zero-cycles

Let KK be a global field with separable closure KsK^s, and let XsX^s be a smooth projective variety over KsK^s. Let CH0(Xs)0\operatorname{CH}_0(X^s)^0 denote the degree-zero Chow group of zero-cycles and let AlbXs\operatorname{Alb}_{X^s} be the Albanese variety. Beilinson's conjecture. The Albanese map

CH0(Xs)0AlbXs(Ks)\operatorname{CH}_0(X^s)^0\longrightarrow \operatorname{Alb}_{X^s}(K^s)

is an isomorphism. This conjecture is used to prove finiteness of the cokernel of ρd\rho_d; the source states that Beilinson formulated it for number fields, while here it is considered over global fields.
