Double Copy from Homotopy Algebras

Fortschritte der Physik, Volume 69, Issue 8-9, September 2021., 2021
It will be shown that the BRST Lagrangian double copy construction of N = 0 supergravity as the ‘square’ of Yang–Mills theory finds a natural interpretation in terms of homotopy algebras. The authors significantly expand on their previous work arguing the validity of the double copy at the loop level, and they give a detailed derivation of the double ...

Quantum log-corrections to swampland conjectures

Journal of High Energy Physics, 2020
Taking the anti-de Sitter minimum of KKLT and the large volume scenario at face value, we argue for the existence of logarithmic quantum corrections to AdS swampland conjectures.

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.

Gauge supergravity in D = 2 + 2

Journal of High Energy Physics, 2017
We present an action for chiral N = (1, 0) supergravity in 2 + 2 dimensions. The fields of the theory are organized into an OSp(1|4) connection supermatrix, and are given by the usual vierbein V a , spin connection ω ab , and Majorana gravitino ψ.

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

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.

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.

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

Superstring Backgrounds in String Geometry

Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021
String geometry theory is a candidate of the nonperturbative formulation of string theory. In order to determine the string vacuum, we need to clarify how superstring backgrounds are described in string geometry theory. In this paper, we show that all the type IIA, IIB, SO(32) type I, and SO(32) and E8 × E8 heterotic superstring backgrounds are ...

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.
