Description

Study of the $HH \to b\bar{b}\gamma\gamma$ decay channel in pp collisions at $\sqrt{s}=13TeV$ and $\sqrt{s}=13.6TeV$ using simulated events from the ATLAS experiment. A neural network classifier is trained on kinematic features to enhance signal-to-background discrimination. Background modeling and diphoton mass reconstruction assumptions, relevant to Higgs boson pair production searches, are investigated.
