Toward Realistic Intersecting D-Brane Models

Annual Review of Nuclear and Particle Science, 2005
We provide a pedagogical introduction to a recently studied class of phenomenologically interesting string models, known as Intersecting D-Brane Models.

Asymptotic scalar field cosmology in string theory

Journal of High Energy Physics, 2022
Asymptotic (late-time) cosmology depends on the asymptotic (infinite-distance) limits of scalar field space in string theory. Such limits feature an exponentially decaying potential V ~ exp(−cϕ) with corresponding Hubble scale H ~ ϕ ̇ 2 + 2 V $$ \sqrt ...

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

Journal 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 ...

Radiative natural supersymmetry emergent from the string landscape

Journal 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.

On asymptotic dark energy in string theory

Journal of High Energy Physics, 2023
We examine bounds on accelerated expansion in asymptotic regions of the moduli space in string theory compactifications to four spacetime dimensions. While there are conjectures that forbid or constrain accelerated expansion in such asymptotic regions ...

String-scale gauge coupling relations in the supersymmetric Pati-Salam models from intersecting D6-branes

Journal of High Energy Physics, 2023
We have constructed all the three-family N $$ \mathcal{N} $$ = 1 supersymmetric Pati-Salam models from intersecting D6-branes, and obtained 33 independent models in total.
