Non-SUSY Searches at ATLAS

TL;DR

This paper reviews the ATLAS experiment's recent searches for new physics beyond the Standard Model using 45 pb^-1 of 2010 data, setting new limits on various hypothetical particles and interactions.

Contribution

It provides the first comprehensive summary of ATLAS's non-SUSY BSM search results, establishing more stringent constraints on multiple models.

Findings

No significant evidence of new physics was observed.

Stringent limits were set on excited quarks, axigluons, and other BSM particles.

Many limits surpass previous experimental constraints.

Abstract

The ATLAS detector has begun the search for new physics beyond the Standard Model (BSM) with \int L dt = ~45 pb^-1 of data collected in 2010. After no significant evidence of new physics was found in the data, limits on possible signatures have been set, many of which have already placed more stringent limits than previous measurements. These proceedings review recent limits obtained on various BSM models, including excited quarks, axigluons, contact interactions, quantum black holes, heavy gauge bosons (W', Z'), gravitons, fourth-generation quarks and leptoquarks.
