Query: Exact solutions for a Maxwell-Kalb-Ramond action with dilaton:
  Localization of massless and massive modes in a sine-Gordon brane-world   We analytically find the exact propagation modes of the electromagnetic and
the Kalb-Ramond fields together in a five-dimensional curved space-time. The
existence and localization of gauge particles into our four-dimensional world
(4D) is studied in detail on a brane-world scenario in which two gauge fields
interact with a dilaton and a gravitational background. The coupling to the
dilaton is different in each case causing the splitting between both gauge
spectra. The gauge field zero-modes and an infinite tower of Kaluza-Klein
massive states are analytically obtained. Relevant conditions on the dilaton
coupling constant are found in order to identify with precision every finite
tensor and vector eigenstate in the theory. An exact quantization condition on
the whole mass spectrum, depending on the dilaton coupling constant and the
bulk Planck mass, is inherited from the extra-dimension. This allows finding an
exact rule to prevent tachyons in the theory and, by the same token, predicting
a possible Kalb-Ramond tensor zero-mode in 4D world. We also show that KK
massive-modes contributions onto 4D physics are strongly suppressed.
