Dijet Searches for New Physics in ATLAS
Georgios Choudalakis
TL;DR
This paper reports on ATLAS searches for new physics using dijet events, updating resonance and angular distribution analyses with recent data, and setting limits on various hypothetical particles.
Contribution
It provides the latest results of dijet resonance and angular distribution searches with new data, including model-independent limits on potential new particles.
Findings
Limits set on excited quarks, axigluons, and scalar color octets.
Updated analysis with larger datasets improves sensitivity.
Model-independent constraints on Gaussian signals.
Abstract
The latest results are presented of the search for new physics in inclusive dijet events recorded with the ATLAS detector. The search for resonances in the dijet mass spectrum is updated with 0.81 fb^-1 of 2011 data. The latest analysis of dijet angular distributions, with 36 pb^-1 of 2010 data, is also presented. In-depth information is provided about the model-independent search for resonances. Limits are provided for excited quarks, axigluons, scalar color octets, and to Gaussian signals that allow to set approximate limits in a model-independent way.
