Search for Large Extra Dimensions in the Production of Jets and Missing Transverse Energy in $p\bar{p}$ Collisions at $\sqrt{s}$ = 1.96 TeV

TL;DR

This paper reports a search for large extra dimensions using jets and missing transverse energy in proton-antiproton collisions, finding no evidence of new physics and setting limits on the fundamental Planck scale.

Contribution

It provides the first experimental limits on large extra dimensions in the jets plus missing energy channel at TeV energies.

Findings

No significant excess of events observed.

Lower limits set on the fundamental Planck scale.

Results constrain models of large extra dimensions.

Abstract

We present the results of a search for new physics in the jets plus missing transverse energy data sample collected from 368 pb^{-1} of ppbar collisions at sqrt{s}=1.96 TeV recorded by the Collider Detector at Fermilab. We compare the number of events observed in the data with a data-based estimate of the Standard Model backgrounds contributing to this signature. We observe no significant excess of events, and we interpret this null result in terms of lower limits on the fundamental Planck scale for a large extra dimensions scenario.
