The dynamics of three-forms in thick branes

open access: yesJournal of High Energy Physics
In this work, we investigate thick brane models with a single three-form field. We find novel solutions for thick braneworlds where only three-forms exist and interact gravitationally in the bulk, both with and without matter fields. We use an additional

Emergence of R 4-terms in M-theory

open access: yesJournal of High Energy Physics
It has been recently suggested that the strong Emergence Proposal is realized in M-theory limits by integrating out all light towers of states with a typical mass scale not larger than the species scale, i.e. the eleventh dimensional Planck mass.

Phenomenology of strong interactions: towards an effective theory for low energy QCD

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
In this paper, we develop models applicable to phenomenological particle physics by using the string analogy of particles. These theories can be used to investigate the phenomenology of confinement, deconfinement, chiral condensate, QGP phase transitions,

Uplifts in the penumbra: features of the moduli potential away from infinite-distance boundaries

open access: yesJournal of High Energy Physics
The construction of meta-stable four-dimensional de Sitter vacua in type IIB string compactifications represents an important question and an ongoing area of work.

Type IIA string theory on T 6/(Z2 × Z6 × OmegaR) : model building and string phenomenology with intersecting D6-branes

open access: yes, 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 ...

End of the world brane networks for infinite distance limits in CY moduli space

open access: yesJournal of High Energy Physics
Dynamical Cobordism provides a powerful method to probe infinite distance limits in moduli/field spaces parameterized by scalars constrained by generic potentials, employing configurations of codimension-1 end of the world (ETW) branes.

Morse-Bott inequalities, topology change and cobordisms to nothing

open access: yesJournal of High Energy Physics
The Cobordism Conjecture predicts spacetime-ending configurations, such as Bubbles of Nothing (BoN), being commonplace. These correspond to vacuum decays in which the compactification manifold C n $$ {\mathcal{C}}_n $$ shrinks to a point, with the ...

Black holes as probes of moduli space geometry

open access: yesJournal of High Energy Physics, 2023
We argue that supersymmetric BPS states can act as efficient finite energy probes of the moduli space geometry thanks to the attractor mechanism. We focus on 4d N $$ \mathcal{N} $$ = 2 compactifications and capture aspects of the effective field theory ...

New comments on six-dimensional orientifold vacua with reduced rank and unitarity constraints

open access: yesJournal of High Energy Physics
We revisit and extend the construction of six-dimensional orientifolds built upon the T 4/ℤ N orbifolds with a non-vanishing Kalb-Ramond background, both in the presence of N $$ \mathcal{N} $$ = (1, 0) supersymmetry and Brane Supersymmetry Breaking, thus

Derivative corrections to extremal black holes with moduli

open access: yesJournal of High Energy Physics, 2023
We derive formulas for the leading mass, entropy, and long-range self-force corrections to extremal black holes due to higher-derivative operators. These formulas hold for black holes with arbitrary couplings to gauge fields and moduli, provided that the
