The paper “Supersymmetric dS_n solutions for n>5 in D = 11 supergravity“, co-authored by Daniele Farotti and Jan Gutowski, has been published gold open access in the Journal of Physics A: Mathematical and Theoretical (link here). In the paper, they determine the necessary and sufficient conditions for warped product dS_n solutions, 5 ⩽ n ⩽ 10, to preserve supersymmetry in D = 11 supergravity, without assuming factorization of the Killing spinors.
