Shadows of 5D Black Holes from String Theory

Autor: Belhaj, A., Belmahi, H., Benali, M., Hadri, W. El, Moumni, H. El, Torrente-Lujan, E.

We study the shadow behaviors of five dimensional (5D) black holes embedded in type IIB superstring/supergravity inspired spacetimes by considering solutions with and without rotations. Geometrical properties as shapes and sizes are analyzed in terms

Phase Transitions of Quintessential AdS Black Holes in M-theory/Superstring Inspired Models

Autor: Belhaj, A., Balali, A. El, Hadri, W. El, Hassouni, Y., Torrente-Lujan, E.

We study $d$-dimensional $AdS$ black holes surrounded by Dark Energy (DE), embedded in $D$-dimensional M-theory/superstring inspired models having $AdS_d \times \mathbb{S}^{d+k}$ space-time with $D=2d+k$. We focus on the thermodynamic Hawking-Page ph

Black holes and general Freudenthal transformations

Autor: Borsten, L., Duff, M. J., Fernández-Melgarejo, J. J., Marrani, A., Torrente-Lujan, E.

We study General Freudenthal Transformations (GFT) on black hole solutions in Einstein-Maxwell-Scalar (super)gravity theories with global symmetry of type $E_7$. GFT can be considered as a 2-parameter, $a, b\in {\mathbb R}$, generalisation of Freuden

The discovery by the ATLAS and CMS experiments of a new boson with mass around 125 GeV and with measured properties compatible with those of a Standard-Model Higgs boson, coupled with the absence of discoveries of phenomena beyond the Standard Model

The Higgs mass coincidence problem: why is the higgs mass $m_H^2=m_Z m_t$?

Autor: Torrente-Lujan, E.

On the light of the recent LHC boson discovery, we present a phenomenological evaluation of the ratio $\rho_t=m_Z m_t/m_H^2$, from the LHC combined $m_H$ value, we get ($ (1\sigma)$) $$\rho_t^{(exp)}= 0.9956\pm 0.0081.$$ This value is close to one wi
