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.

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.

Landscape of modular symmetric flavor models
Journal of High Energy Physics, 2021 We study the moduli stabilization from the viewpoint of modular flavor symmetries. We systematically analyze stabilized moduli values in possible configurations of flux compactifications, investigating probabilities of moduli values and showing which ...

Journal of High Energy Physics, 2019 We investigate neutralino dark matter from a string/M-theory perspective. Using the Kallosh-Linde (KL) scenario to stabilize the string moduli requires supersymmetry breaking for uplifting to a de Sitter vacuum.

Unity of pomerons from gauge/string duality
Journal of High Energy Physics, 2017 We develop a formalism where the hard and soft pomeron contributions to high energy scattering arise as leading Regge poles of a single kernel in holographic QCD.

, 2016 In this doctoral thesis, various aspects of string model building and phenomenology are investigated within the framework of Type IIA string theory on the T 6/(Z2 × Z6 × ΩR) orbifold with discrete torsion. The aim is the reproduction of supersymmetric versions of well-known particle physics models using intersecting rigid D6-branes wrapped on ...

Searching for axion-like particles with proton tagging at the LHC
Journal of High Energy Physics, 2018 The existence of an axion-like particle (ALP) would induce anomalous scattering of light by light. This process can be probed at the Large Hadron Collider in central exclusive production of photon pairs in proton-proton collisions by tagging the ...

Hidden sectors in string theory: kinetic mixings, fifth forces and quintessence
Journal of High Energy Physics, 2019 Light moduli fields in string compactifications can have interesting implications for particle physics and cosmology. Fifth force bounds impose stringent constraints on the interactions of such moduli with the visible sector.
