String (Gravi)photons, “Dark Brane Photons”, Holography and the Hypercharge Portal
Fortschritte der Physik, Volume 69, Issue 6, June 2021., 2021 Abstract The mixing of graviphotons and dark brane photons to the Standard Model hypercharge is analyzed in full generality, in weakly‐coupled string theory. Both the direct mixing as well as effective terms that provide mixing after inclusion of SM corrections are estimated to lowest order.

A Note on Toroidal Compactifications of the Type I Superstring and Other Superstring Vacuum Configurations with 16 Supercharges [PDF]
, 1997 We show that various disconnected components of the moduli space of superstring vacua with 16 supercharges admit a rationale in terms of BPS un-orientifolds, i.e.

An Effective Model for Glueballs and Dual Superconductivity at Finite Temperature
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 The glueballs lead to gluon and QCD monopole condensations as by‐products of color confinement. A color dielectric function G(∣ϕ∣) coupled with a Abelian gauge field is properly defined to mediate the glueball interactions at confining regime after spontaneous symmetry breaking (SSB) of the gauge symmetry. The particles are expected to form through the

String Phenomenology: Past, Present and Future Perspectives [PDF]
, 2014 The observation of a scalar resonance at the LHC, compatible with perturbative electroweak symmetry breaking, reinforces the Standard Model parameterisation of all subatomic data.

Searching the landscape of flux vacua with genetic algorithms
Journal of High Energy Physics, 2019 In this paper, we employ genetic algorithms to explore the landscape of type IIB flux vacua. We show that genetic algorithms can efficiently scan the landscape for viable solutions satisfying various criteria. More specifically, we consider a symmetric T

Aspects of Semiclassical Black Holes: Development and Open Problems
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 The current work is a review, dedicated to the study of semiclassical aspects of black holes. We begin by briefly looking at the main statements of general relativity. We then consider the Schwarzschild, Kerr, and Reissner‐Nordstrom black hole solutions and discuss their geometrical properties.

BPS Saturated Dyonic Black Holes of $N=8$ Supergravity Vacua [PDF]
, 1995 We summarize the results for four-dimensional Bogomol'nyi-Prasad- Sommerfield (BPS) saturated dyonic black hole solutions arising in the Kaluza-Klein sector and the three-form field sector of the eleven-dimensional supergravity on a seven-torus.

Swampland variations on a theme by KKLT
Journal of High Energy Physics, 2019 The KKLT scenario in a warped throat, if consistent, provides a concrete counterexample to both the AdS scale separation and the dS swampland conjectures.

de Sitter vacua from ten dimensions
Journal of High Energy Physics, 2021 We analyze the de Sitter construction of [1] using ten-dimensional supergravity, finding exact agreement with the four-dimensional effective theory. Starting from the fermionic couplings in the D7-brane action, we derive the ten-dimensional stress-energy
