Title: Higgs physics with Neural Simulation-Based Inference at the LHC and in ATLAS
Abstract: Neural Simulation-Based Inference (NSBI) is a powerful class of machine learning (ML)-based methods for statistical inference that naturally handle high dimensional parameter estimation without the need to bin data into low-dimensional summary histograms. Such methods are promising for a range of measurements, including at the Large Hadron Collider (LHC), where no single observable may be optimal to scan over the entire theoretical phase space under consideration, or where binning data into histograms could result in a loss of sensitivity. This work develops an NSBI framework for statistical inference, using neural networks to estimate probability density ratios, that enables the application of NSBI to a full-scale LHC analysis, by incorporating a large number of systematic uncertainties, quantifying the uncertainty coming from finite training statistics, developing a method to construct confidence intervals, and demonstrating a series of intermediate diagnostic checks that can be performed to validate the robustness of the method. As an example, the power and feasibility of the method is demonstrated for an off-shell Higgs boson couplings measurement in the four leptons final states. The method is an extension of the standard statistical framework used by LHC experiments, and can benefit a large number of physics analyses. (2:00 PM - 3:00 PM, 726 Broadway, 940, CCPP Seminar)
