Relaxation of the cosmological constant in a movable brane world
Physics Letters B 551,3-4 (2003) 211-217;
We present numerical evidence that a domain wall in a background with varying vacuum energy density acquires velocity in the direction of decreasing Hubble parameter. This should lead to at least a partial relaxation of the cosmological constant on the wall. (C) 2002 Published by Elsevier Science B.V.
