Deficit Hawks -- or, How to Stop Worrying and Love the Unknown Backgrounds – Jelle Aalbers (Stanford)

virtual (SLAC)




Can experiments with unknown backgrounds still produce robust constraints on new physics? The answer is yes -- with appropriate statistical techniques. I will review existing approaches, then introduce the 'deficit hawk' method, which allows analysts to leverage partial or speculative background knowledge. Deficit hawks simplify decisions on fiducial volumes and energy thresholds, are well-suited to analyses that use machine learning or multidimensional likelihoods, and permit discoveries in regions without unknown backgrounds.
