Description
Resonant anomaly detection is a promising strategy for extending the reach of bump-hunt searches at the LHC. In a weakly supervised setup, a high-quality background template is essential to produce an anomaly score but can serve a second purpose: It allows to directly estimate the background expectation in a simple cut and count setup, removing the problem of background sculpting. For imperfect background templates, the expected number of selected events from the signal region and, in particular, the corresponding systematic uncertainty needs to be well understood. I will present an improved, statistically robust determination of these quantities and discuss the resulting sensitivity of the method.
