String Phenomenology at the LHC

TL;DR

This paper explores how string theory extensions of the standard model could produce detectable signals at the LHC, assuming TeV-scale string masses and weak coupling.

Contribution

It reviews potential experimental signatures of open string models with D-branes at the TeV scale in collider experiments.

Findings

Possible string signals at the LHC identified

Implications for TeV-scale string theories discussed

Guidelines for experimental searches provided

Abstract

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 review possible signals of string physics at the Large Hadron Collider.
