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

European 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,

Brane-World Gravity. [PDF]

Living Rev Relativ, 2010
The observable universe could be a 1+3-surface (the “brane”) embedded in a 1+3+d-dimensional spacetime (the “bulk”), with Standard Model particles and fields trapped on the brane while gravity is free to access the bulk.

D-branes at Singularities and String Phenomenology

Nuclear Physics B - Proceedings Supplements, 2007
In these notes we give an introduction to some of the concepts involved in constructing SM-like gauge theories in systems of branes at singularities of CY manifolds. These notes are an expanded version of lectures given by Herman Verlinde at the Cargese 2006 Summer School.

The emergence proposal and the emergent string

Journal of High Energy Physics, 2023
We explore the Emergence Proposal for the moduli metric and the gauge couplings in a concrete model with 7 saxionic and 7 axionic moduli fields, namely the compactification of the type IIA superstring on a 6-dimensional toroidal orbifold.

Cobordism, singularities and the Ricci flow conjecture

Journal of High Energy Physics, 2023
In the following work, an attempt to conciliate the Ricci flow conjecture and the Cobordism conjecture, stated as refinements of the Swampland distance conjecture and of the No global symmetries conjecture respectively, is presented.

Kination, meet Kasner: on the asymptotic cosmology of string compactifications

Journal of High Energy Physics, 2023
We study runaway, kination-dominated epochs in string cosmology. We show how the apparent classical decompactification runaway of the volume modulus, described by a kination epoch in the 4-dimensional EFT, can be uplifted to a classical Kasner solution ...

String Phenomenology 2019

, 2019
An anti-D3-brane plays a crucial role in the construction of semi-realistic cosmological models in string theory. Part of its action provides an uplift term that has been used to lift AdS solutions to phenomenological viable dS vacua in the KKLT and LVS ...

α′ corrections to KPV: an uplifting story

Journal of High Energy Physics, 2023
In earlier work, the effect of α′2 curvature corrections on the NS5-brane responsible for the decay of anti-D3-branes in the set-up of Kachru, Pearson, and Verlinde (KPV) was considered. We extend this analysis to include all known α′2 corrections to the

The supersymmetry breaking soft terms, and fermion masses and mixings in the supersymmetric Pati-Salam model from intersecting D6-branes

Journal of High Energy Physics, 2022
A supersymmetric Pati-Salam model with wrapping number equal to 5 has been constructed in Type IIA orientifolds on T 6 /(ℤ 2 × ℤ 2) with intersecting D6-branes recently.
