A key challenge in searches for resonant new physics is that classifiers trained to enhance potential signals must not induce localized structures. Such structures could result in a false signal when the background is estimated from data using sideband methods. A variety of techniques have been developed to construct classifiers which are independent from the resonant feature (often a mass). Such strategies are sufficient to avoid localized structures, but are not necessary. We develop a new…

Controlling Classifier Bias with Moment Decomposition: A Method to Enhance Searches for Resonances
A key challenge in searches for resonant new physics is that classifiers trained to detect and enhance potential signals must not induce localized structures, i.e. they must not sculpt a peak in an

Dijet Resonance Search with Weak Supervision Using sqrt[s]=13  TeV pp Collisions in the ATLAS Detector.
A search for narrowly resonant new physics using a machine-learning anomaly detection procedure that does not rely on signal simulations for developing the analysis selection and results are complementary to the dedicated searches for the case that B and C are standard model bosons.

Automating the ABCD method with machine learning significantly improves performance in terms of ABCD closure, background rejection and signal contamination, and uncovers a previously unappreciated aspect of the method: its accuracy hinges on having low signal contamination in control regions not just overall, but relative to the signal fraction in the signal region.
