Commissioning and evolution of the Run 3 ATLAS Trigger / Nobe, Takuya (University of Tokyo (JP))
The ATLAS experiment in the LHC Run 3 uses a two-level trigger system to select events of interest to reduce the 40 MHz bunch crossing rate to a recorded rate of up to 3 kHz of fully-built physics events. [...]

Effective field theory interpretations of the search for $HH\rightarrow b\bar{b}\gamma\gamma$ with 308 fb$^{-1}$ of data collected at $\sqrt{s} = 13$ TeV and 13.6 TeV with the ATLAS detector
This note presents interpretations of a search for Higgs boson pair production in the $b\bar{b}\gamma\gamma$ final state using the Standard Model Effective Field Theory (SMEFT) and Higgs Effective Field Theory (HEFT) frameworks. [...]
