The Gersten conjecture for Witt groups in the equicharacteristic case, by Paul Balmer, Stefan Gille, Ivan Panin, and Charles Walter

We prove the Gersten conjecture for Witt groups in the equicharacteristic case, that is for regular local rings containing a field of characteristic not 2. This uses some triangular Witt groups, some devissage results for Gersten-Witt spectral sequences, some transfers, some reformulation of the conjecture in terms of Zariski cohomology and some Popescu theorem.
