Some Phenomenology of Intersecting D-Brane Models

, 2004
We present some phenomenology of a new class of intersecting D-brane models. Soft SUSY breaking terms for these models are calculated in the u - moduli dominant SUSY breaking approach (in type IIA).

Un-oriented Quiver Theories for Majorana Neutrons [PDF]

, 2015
In the context of un-oriented open string theories, we identify quivers whereby a Majorana mass for the neutron is indirectly generated by exotic instantons. We discuss two classes of (Susy) Standard Model like quivers, depending on the embedding of SU(2)

Constraints on LVS Compactifications of IIB String Theory

, 2012
We argue that once all theoretical and phenomenological constraints are imposed on the different versions of the Large Volume Scenario (LVS) compactifications of type IIB string theory, one particular version is favored. This is essentially a sequestered

Seeking the Ground State of String Theory [PDF]

, 1999
Recently, a number of authors have challenged the conventional assumption that the string scale, Planck mass, and unification scale are roughly comparable. It has been suggested that the string scale could be as low as a TeV.

The dynamics of three-forms in thick branes

Journal 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

A Review of Distributions on the String Landscape [PDF]

, 2006
We review some basic flux vacua counting techniques and results, focusing on the distributions of properties over different regions of the landscape of string vacua and assessing the phenomenological implications.

Emergence of R 4-terms in M-theory

Journal 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

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,

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

Journal 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.

TeV-Scale strings

, 2014
This article discusses the status of string physics where the string tension is around the TeV scale. The article covers model building basics for perturbative strings, based on D-brane configurations. The effective low energy physics description of such
