Namely, by performing a suitable decomposition of the vector field, the resulting 4D effective action corresponds to a massive gauge field, while the profile along the extra dimension obeys a Schrodinger-like equation with a Poschl-Teller potential. It turns out that the massless zero mode of the gauge field is bound to the expanding 3-brane and allows us to recover the standard 4D electromagnetic phenomena of our world. Moreover, this zero mode is separated from the continuum of Kaluza-Klein (KK) modes by a mass gap determined by the scale of the expansion parameter. We also were able to analytically solve the corresponding Schrodinger-like equation for arbitrary mass, showing that KK massive modes asymptotically behave like plane waves, as expected.", optnote="WOS:000334449800001", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=1751), last updated on Fri, 16 May 2014 12:19:09 +0000", issn="1434-6044", doi="10.1140/epjc/s10052-014-2770-1", opturl="http://arxiv.org/abs/arXiv:1401.0999", opturl="https://doi.org/10.1140/epjc/s10052-014-2770-1", archivePrefix="arXiv", eprint="arXiv:1401.0999", language="English" }
