CPT Student Seminar: Distinguishing b-quark and gluon jets with a tagged b-hadron
7 March 2016 17:00 in OC218
b-tagged jets, i. e. jets containing a b-hadron, are an important final state at high energy particle colliders, providing insight into some of the more interesting Standard Model processes as well as opening up a channel to test many BSM physics scenarios. I will spend some time reviewing the techniques and current status of b-tagging, focussing on the general purpose detectors ATLAS and CMS, a topic that is often glossed over in theory classes. I will then move on to motivate why simple b-tagging might not be the end of the story, as it does not discriminate against the large QCD backgrounds from gluon splitting. I will show how jet substructure observables can be used to distinguish these cases and will introduce a new observable that might improve the current methods considerably.
