On The Problem of Vacuum energy in Brane Theories
Ilya Gurwich, Shimon Rubin, Aharon Davidson
We point out that modern brane theories suffer from a severe vacuum energy problem. To be specific, the Casimir energy associated with the matter fields confined to the brane, is s…

Brane Gravitational Extension of Dirac's "Extensible Model of the Electron"
Aharon Davidson, Shimon Rubin
A gravitational extension of Dirac's "Extensible model of the electron" is presented. The Dirac bubble, treated as a 3-dim electrically charged brane, is dynamically embedded withi…

Zero Cosmological Constant from Normalized General Relativity
Aharon Davidson, Shimon Rubin
Normalizing the Einstein-Hilbert action by the volume functional makes the theory invariant under constant shifts in the Lagrangian. The associated field equations then resemble un…
