Subject: Quark-gluon jet discrimination and its applications at the LHC

The discrimination of quark- and gluon-initiated jets is a topic being actively explored by the ATLAS and CMS collaborations, with potential applications to physics searches at the LHC. In this talk, I shall give a brief overview of observables sensitive to quark and gluon jet sub-structure, the current understanding and challenges in predicting them using Monte Carlo tools, and how some of those challenges can be overcome using data-driven templates being derived by the LHC experiments. I shall then illustrate the potential impact of quark-gluon tagging in physics searches, taking the example of gluino pair production at the LHC.
