Axion induced angular momentum reversal in Kerr-like black holes
TL;DR: In this paper , a pseudoscalar axion-like field coupled to a Chern-Simons gravitational anomaly term is considered, and the axion field backreacts on a rotating Kerr black hole background, resulting in modifications in the spacetime.
Journal ArticleDOI
Probing the holography of near-horizon AdS5 × S5 geometry
TL;DR: In this paper, the authors study the holographic principle and the CFT/FRW relations in the near-horizon AdS5×S5 geometry with a probe D3-brane playing the role of the boundary to this space.
Journal ArticleDOI
Perturbations of Gauss-Bonnet black strings in codimension-2 braneworlds
Bertha Cuadros-Melgar,Eleftherios Papantonopoulos,Minas Tsoukalas,Vassilios Zamarias,Vassilios Zamarias +4 more
TL;DR: In this article, the authors derived the modified Lichnerowicz equation in the presence of the Gauss-Bonnet term and studied the metric perturbations of GaussBonnet black strings in Codimension-2 Braneworlds.
Journal ArticleDOI
On the suppression of flavour changing neutral processes in technicolour theories
TL;DR: In this article, a mechanism for the suppression of flavour changing neutral currents in theories with technicolour was presented, in a form of a theorem, and illustrated toy models were considered as an implementation of such a mechanism.
Journal ArticleDOI
Four-Dimensional Asymptotically AdS Black Holes with Scalar Hair
TL;DR: In this paper, a new family of asymptotically AdS four-dimensional black hole solutions with scalar hair of a gravitating system consisting of a scalar field minimally coupled to gravity with a self-interacting potential is presented.
