Abstract

We consider self-consistent coupling of the recently introduced new class of Weyl-conformally invariant lightlike branes (WILL-branes) to D = 4 Einstein-Maxwell system plus a D -4 three-index antisymmetric tensor gauge field. We find static spherically-symmetric solutions where the space-time consists of two regions with different black-hole-type geometries and different values for a dynamically generated cosmological constant, separated by the WILL-brane which "straddles" their common event horizon. Furthermore, the WILL-brane produces a potential "well" around itself acting as a trap for test particles falling towards the horizon.
