Abstract
A search for quantum black holes with color charge decaying to one electron and
one quark has been performed using data collected by the ATLAS Experiment at
the Large Hadron Collider corresponding to 2.29 fb−1. No excess over the expected
Standard Model interactions has been observed. Limits are set on the production
cross section for events with one electron and one jet resulting from new physical
phenomena. Models with a combined invariant mass of the electron and jet larger
than or equal to 2.5TeV and a cross section above 2.6 fb are excluded at the 95%
confidence level. This allows the exclusion of a significant part of the parameter
space of quantum black hole models.
