Antisymmetric Tensor Fields in Randall Sundrum Thick Branes
In this article we study the issue of localization of the three-form field in
a Randall-Sundrum-like scenario. We simulate our membrane by kinks embedded in
D=5, describing the usual case (not deformed) and new models coming from a
specific deformation procedure. The gravitational background regarded includes
the dilaton contribution. We show that we can only localize the zero-mode of
this field for a specific range of the dilaton coupling, even in the deformed
case. A study about resonances is presented. We use a numerical approach for
calculations of the transmission coefficients associated to the quantum
mechanical problem. This gives a clear description of the physics involved in
the model. We find in this way that the appearance of resonances is strongly
dependent on the coupling constant. We study the cases and 5 for
and . The first value of give us one
resonance peak for and no resonances for . The second value of
give us a very rich structure of resonances, with number deppending on
the value of .Comment: 7 pages, 3 figure
