"Big" Divisor D3/D7 Swiss Cheese Phenomenology

, 2010
We review progress made over the past couple of years in the field of Swiss Cheese Phenomenology involving a mobile space-time filling D3-brane and stack(s) of fluxed D7-branes wrapping the "big" (as opposed to the "small") divisor in (the orientifold of

Warping and F-term uplifting [PDF]

, 2007
We analyse the effective supergravity model of a warped compactification with matter on D3 and D7-branes. We find that the main effect of the warp factor is to modify the F-terms while leaving the D-terms invariant.

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 ...

Model Building and Phenomenology of Flux-Induced Supersymmetry Breaking on D3-branes

, 2004
We study supersymmetry breaking effects induced on D3-branes at singularities by the presence of NSNS and RR 3-form fluxes. First, we discuss some local constructions of chiral models from D3-branes at singularities, as well as their global embedding in ...

Exotic see-saw mechanism for neutrinos and leptogenesis in a Pati-Salam model [PDF]

, 2016
We discuss non-perturbative corrections to the neutrino sector, in the context of a D-brane Pati-Salam-like model, that can be obtained as a simple alternative to $SO(10)$ GUT's in theories with open and unoriented strings. In such D-brane models, exotic

De Sitter cosmology on an expanding bubble

Journal of High Energy Physics, 2019
Constructing an explicit compactification yielding a metastable de Sitter (dS) vacuum in a UV consistent string theory is an incredibly difficult open problem.

Probing the Green-Schwarz Mechanism at the Large Hadron Collider

, 2007
We investigate the phenomenology of new abelian gauge bosons, which we denote as $X$ bosons, that suffer a mixed anomaly with the Standard Model, but are made self-consistent by the Green-Schwarz mechanism.

Oscillons from string moduli

Journal of High Energy Physics, 2018
A generic feature of string compactifications is the presence of many scalar fields, called moduli. Moduli are usually displaced from their post-inflationary minimum during inflation.

Jumping Through Loops: On Soft Terms from Large Volume Compactifications

, 2007
We subject the phenomenologically successful large volume scenario of hep-th/0502058 to a first consistency check in string theory. In particular, we consider whether the expansion of the string effective action is consistent in the presence of D-branes ...

Magnetic monopoles and free fractionally charged states at accelerators and in cosmic rays

Journal of High Energy Physics, 2017
Unified theories of strong, weak and electromagnetic interactions which have electric charge quantization predict the existence of topologically stable magnetic monopoles.
