Dark Dimension With (Little) Strings Attached

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract A relation between dark energy and the scale of new physics in weakly coupled string theory is motivated. This mixing between infrared and ultraviolet physics leads to a unique corner for real‐world phenomenology: barring fine‐tunings, the authors are naturally led to the “dark dimension” scenario, a single mesoscopic extra dimension of micron

Inclusive production through AdS/CFT

Journal of High Energy Physics, 2017
It has been shown that AdS/CFT calculations can reproduce certain exclusive 2→2 cross sections in QCD at high energy, both for near-forward and for fixed-angle scattering.

Continuum-mediated self-interacting dark matter

Journal of High Energy Physics, 2021
Dark matter may self-interact through a continuum of low-mass states. This happens if dark matter couples to a strongly-coupled nearly-conformal hidden sector.

Constraining the string scale: from Planck to Weak and back again

, 2004
String and field theory ideas have greatly influenced each other since the so called second string revolution. We review this interrelation paying particular attention to its phenomenological implications.

Notes on Characterizations of 2d Rational SCFTs: Algebraicity, Mirror Symmetry, and Complex Multiplication

Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.
Abstract S. Gukov and C. Vafa proposed a characterization of rational N=(1,1)$N=(1,1)$ superconformal field theories (SCFTs) in 1+1$1+1$ dimensions with Ricci‐flat Kähler target spaces in terms of the Hodge structure of the target space, extending an earlier observation by G. Moore.

Categorisation and detection of dark matter candidates from string/M-theory hidden sectors

Journal of High Energy Physics, 2018
We study well-motivated dark matter candidates arising from weakly-coupled hidden sectors in compactified string/M-theory. Imposing generic top-down constraints greatly restricts allowed candidates.

D Branes and Textures [PDF]

, 2000
We examine the flavor structure of the trilinear superpotential couplings which can result from embedding the Standard Model within D brane sectors in Type IIB orientifold models, which are examples within the Type I string framework.

q‐Deformed Glueball Spectrum in AdS/QCD Correspondence

Advances in High Energy Physics, Volume 2024, Issue 1, 2024.
This work presents the application of the q‐algebra in the glueball spectrum. This algebra is implemented through Jackson’s derivatives in a Schrödinger‐like equation resulting from the gravity fluctuations around the braneworld scenario in five dimensions.

Neutralino dark matter in scenarios with early matter domination

Journal of High Energy Physics, 2018
We investigate the production of neutralino dark matter in a cosmological scenario featuring an early matter dominated era ending at a relatively low reheating temperature.

Gravity-mediated dark matter in clockwork/linear dilaton extra-dimensions

Journal of High Energy Physics, 2020
We study for the first time the possibility that Dark Matter (represented by particles with spin 0, 1/2 or 1) interacts gravitationally with Standard Model particles in an extra-dimensional Clockwork/Linear Dilaton model.
