- Abstract: Abstract 1: Search for New Physics via Higgs Boson Pair Production Higgs boson pair production provides a direct probe of the Higgs self-coupling and potential physics beyond the Standard Model (BSM). This study explores non-resonant HH production, focusing on constraints from collider data and theoretical models. Key results highlight the sensitivity of current and future experiments to BSM phenomena through precise measurements of the HH production cross-section and kinematic distributions.
Abstract 2: Novel Machine Learning Methods in High-Energy Physics This work introduces innovative semi-weakly supervised machine learning techniques for enhancing sensitivity to rare physics processes in collider experiments. By leveraging neural networks tailored to domain-specific features, the approach improves signal extraction and classification efficiency. Applications to simulated and real data demonstrate the effectiveness of these methods in uncovering subtle signatures of new physics phenomena. - Host: Sau Lan Wu
