Focused workshop on AI in High Energy Physics

→ Asia/Seoul
Description

Data from particle physics is unique and challenging due to its tremendous size and complicated structure stemming  from its quantum nature.

The goal of this focus-workshop is to develop novel techniques for the future exploration of new physics, exploring exciting developments in the field of Artificial Intelligence.

The structure of the workshop is designed to survey the core questions in new physics searches and to stimulate intense discussion/collaboration among participants. 

We encourage young researchers and Ph.D students to register and to talk / discuss about their researches with experts.

        Detecting Light Fermiophobic Higgs Boson through CNN-based Diphoton Jet Analysis at the HL-LHC

        This talk presents a novel approach to detect a light fermiophobic Higgs boson (hf) with mass in the range of 1-10 GeV at the HL-LHC, focusing on the golden channel p p → hf H → γγγγℓν. Due to the highly collimated nature of photon pairs from hf decay, traditional detection methods face significant challenges as these photons manifest as single jets rather than isolated photons. We introduce an innovative strategy utilizing Convolutional Neural Networks (CNN) to identify these distinctive diphoton jets and distinguish them from QCD backgrounds. Our method employs the Delphes framework's EFlow objects, combined with a hybrid pileup subtraction technique that merges charged hadron subtraction with SoftKiller. The analysis demonstrates remarkable results across 18 benchmark points, achieving signal significance above 5σ at an integrated luminosity of 3 ab⁻¹. For challenging scenarios involving heavy charged Higgs bosons, our CNN-based approach significantly enhances detection capability, nearly doubling the significance compared to traditional cut-based methods. This study opens new possibilities for exploring previously challenging parameter spaces in BSM physics through machine learning techniques.
