Is the electric charge conserved in brane world? Authors: S.L. Dubovsky, V.A. Rubakov, P.G. Tinyakov
We discuss whether electric charge conservation may not hold in four-dimensional world in
models with infinite extra dimensions, i.e., whether escape of charged particles from our brane is
consistent with effectively four-dimensional electrodynamics on the brane. We introduce a setup
with photon localized on the brane and show that charge leakage into extra dimension is allowed
within this setup. The electric field induced on the brane by escaping charge does not obey
four-dimensional Maxwell's equations; this field gradually disappears in a causal way. We also
speculate on the possibility of the escape of colored particles and formation of colorless free quark
states on the brane.
