String Theory at LHC Using Supersymmetry Production From String Balls

TL;DR

This paper explores how string balls, if produced at the LHC due to TeV-scale string physics, could significantly enhance supersymmetry particle production, serving as a potential signature of extra dimensions.

Contribution

It introduces the idea that string ball production can lead to increased supersymmetry particle yields at the LHC, providing a novel signature for TeV-scale string theories.

Findings

String ball production yields are comparable to pQCD predictions.

Enhanced supersymmetry production could indicate TeV-scale string physics.

Absence of black hole signals makes string ball signatures more prominent.

Abstract

If extra dimensions are found in the second run of LHC in the $pp$ collisions at $\sqrt{s}$ = 14 TeV then the string scale can be $\sim$ TeV, and we should produce string balls at LHC. In this paper we study supersymmetry (squark and gluino) production from string balls at LHC in $pp$ collisions at $\sqrt{s}$ = 14 TeV and compare that with the parton fusion results using pQCD. We find significant squark and gluino production from string balls at LHC which is comparable to parton fusion pQCD results. Hence, in the absence of black hole production at LHC, an enhancement in supersymmetry production can be a signature of TeV scale string physics at LHC.
