Query: Can thick braneworlds be self-consistent?   We discuss the backreaction of a massless, minimally coupled, quantized
scalar field on a thick, two-dimensional de Sitter (dS) brane as an extension
of our previous work. We show that a finite brane thickness naturally
regularizes the backreaction on the brane. The quantum backreaction exhibits a
quadratic divergence in the thin wall limit. We also give a theoretical bound
on the brane thickness, in terms of the brane self-consistency of the quantum
corrected Einstein equation, namely the requirement that the size of the
backreaction should be smaller than that of the background stress-energy at the
center of the brane. Finally, we discuss the brane self-consistency for the
case of a four-dimensional dS brane.
