Ultra High Jet Signals from Stringy No-Scale Supergravity

TL;DR

This paper identifies distinctive ultra-high jet signatures from string-inspired supergravity models with light stop and gluino particles, proposing specific LHC search strategies to detect these unique signals.

Contribution

It introduces a novel signature of stringy no-scale supergravity models characterized by ultra-high jet multiplicities, guiding experimental searches at the LHC.

Findings

Light stop and gluino are lighter than other squarks.

Optimal detection occurs with 9 or more jets.

Exclusion of key cuts reduces signal visibility.

Abstract

We present distinctive signatures of flipped F-Theory models with TeV-scale vector-like particles, a \sqrt{s} = 7 TeV 1 fb^{-1} test at LHC of a class of models well-motivated from string theory. The characteristic feature is a light stop and gluino, both sparticles lighter than all other squarks. This unique aspect of the supersymmetry spectrum generates an ultra-high multiplicity of hadronic jets. We find the optimal signal to background ratio is realized for 9 or more jets. Exclusion of the essential cuts presented here could leave the ultra-high jet signal severely attenuated and concealed.
