String phenomenology from a worldsheet perspective [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
I argue that the ten dimensional non-supersymmetric tachyonic superstrings may serve as good starting points for the construction of viable phenomenological vacua.

ASPECTS OF STRING PHENOMENOLOGY IN PARTICLE PHYSICS AND COSMOLOGY [PDF]

open access: yesOdessa Astronomical Publications, 2016
We discuss possible connections between several scales in particle physics and cosmology, such the the electroweak, inflation, dark energy and Planck scales.

String phenomenology

open access: yes, 2015
Abstract This chapter reviews a number of topics in the field of string phenomenology, focusing on orientifold/F-theory models yielding semirealistic low-energy physics. The emphasis is on the extraction of the low-energy effective action and possible tests of specific models at the LHC.

LHC string phenomenology [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 2007
We argue that it is possible to address the deeper LHC Inverse Problem, to gain insight into the underlying theory from LHC signatures of new physics. We propose a technique which may allow us to distinguish among, and favor or disfavor, various classes of underlying theoretical constructions using (assumed) new physics signals at the LHC.

Fine-tuned vs. natural supersymmetry: what does the string landscape predict?

open access: yesJournal of High Energy Physics, 2022
A vast array of (metastable) vacuum solutions arise from string compactifications, each leading to different 4-d laws of physics. The space of these solutions, known as the string landscape, allows for an environmental solution to the cosmological ...

LHC phenomenology for string hunters [PDF]

open access: yesNuclear Physics B, 2009
We consider extensions of the standard model based on open strings ending on D-branes, with gauge bosons due to strings attached to stacks of D-branes and chiral matter due to strings stretching between intersecting D-branes. Assuming that the fundamental string mass scale is in the TeV range and the theory is weakly coupled, we discuss possible ...

Quantum supergravity, supergravity anomalies and string phenomenology

open access: yesNuclear Physics B, 2016
I discuss the role of quantum effects in the phenomenology of effective supergravity theories from compactification of the weakly coupled heterotic string. An accurate incorporation of these effects requires a regularization procedure that respects local

Radiative natural supersymmetry emergent from the string landscape

open access: yesJournal of High Energy Physics, 2022
In string theory with flux compactifications, anthropic selection for structure formation from a discretuum of vacuum energy values provides at present our only understanding of the tiny yet positive value of the cosmological constant.

Δ(54) flavor phenomenology and strings [PDF]

open access: yesJournal of High Energy Physics, 2016
Delta(54) can serve as a flavor symmetry in particle physics, but remains almost unexplored. We show that in a classification of semi-realistic Z3xZ3 heterotic string orbifolds, Delta(54) turns out to be the most natural flavor symmetry, providing additional motivation for its study.
