Kalb–Ramond excitations in a thick-brane scenario with dilaton

HR Christiansen, MS Cunha - The European Physical Journal C, 2012 - Springer
We compute the full spectrum and eigenstates of the Kalb–Ramond field in a warped non-
compact Randall–Sundrum-type five-dimensional spacetime in which the ordinary four …

Space–time filling branes in non-critical (super) string theories

AR Lugo, MB Sturla - Nuclear physics B, 2008 - Elsevier
We consider solutions of (super) gravities associated to non-critical (super) string theories in
arbitrary space–time dimension D= p+ 3, that describe generically non-extremal black p …

Brane Physics in Non-Critical Theories

MB Sturla - arXiv preprint arXiv:1009.5668, 2010 - arxiv.org
In this Thesis, we focus on the study of the low energy approximation to non-critical string
theories. We present an exhaustive study of their solutions, which are divided in three cases …

Gauge invariant perturbation theory and non-critical string models of Yang-Mills theories

AR Lugo, MB Sturla - Journal of High Energy Physics, 2010 - Springer
We carry out a gauge invariant analysis of certain perturbations of D− 2-branes solutions of
low energy string theories. We get generically a system of second order coupled differential …
