The ATLAS detector relies on its liquid-argon (LAr) calorimeter to measure the energies of electrons and photons produced in proton–proton collisions at the LHC. After the high-luminosity upgrade of the LHC, the calorimeter will face substantially increased background activity from many overlapping signals produced in nearby bunch crossings, complicating real-time energy reconstruction. To...

Electroweak production of a Z boson in association with two jets (EW Zjj) provides a clean way of probing vector boson fusion (VBF) and serves as a sensitive test of electroweak couplings within the Standard Model at high energies. Using the ATLAS detector at the Large Hadron Collider, this analysis aims to measure differential cross-sections of key observables in the dilepton channel and to...

The Higgs self-coupling, as related to the shape of the Higgs potential, is central to several fundamental questions, such as the dynamics of the early universe, its expansion and cooling, and the origin of baryon asymmetry. By analyzing di-higgs events that occur during proton-proton collisions in the ATLAS experiment, observed bounds have been placed on this self-coupling value, but remain...

The Standard Model (SM) predicts pair production of the Higgs boson, but it has not yet been observed. The physics involved in the creation of Higgs pairs can address numerous open questions in the SM.
There are several searches for Higgs pairs at the ATLAS detector, where they are formed primarily through gluon-gluon fusion (ggF), and the largest decay channel is to b-quark jets. Thus,...

At Belle II, $B$ mesons are produced in pairs nearly at rest. The Full Event Interpretation (FEI), a machine-learning based background-suppression method, reconstructs one of the $B$ mesons in a well-known decay mode (the tag side). The remaining particles in the event are then used to reconstruct the signal $B$ meson.
The Semileptonic FEI uses a hierarchical decay-chain reconstruction in...

The MOLLER experiment aims to constrain fundamental parameters in the Standard Model by measuring the parity-violating asymmetry A$_{\rm PV}$ induced by the interference between electromagnetic and weak neutral current amplitudes. MOLLER will utilize polarized Møller scattering at Jefferson Lab to measure a highly precise 0.8 part per billion (ppb) uncertainty on the predicted 33 ppb A$_{\rm...

The MOLLER experiment at Jefferson Lab will measure the weak mixing angle with unprecedented precision via parity-violating Møller scattering. A major engineering challenge is mitigating radiation damage to the spectrometer coils and their S2-glass/CTD-403 insulation.
The upstream and downstream regions receive radiation levels beyond acceptable limits, necessitating the implementation of...

AI is everywhere, but a theoretical understanding of AI behaviour is still lacking. In this talk I will show how high-energy physics, in particular our well-understood data structures, can help open the black box of AI. Closing the circle, a better understanding of AI will help us use AI to better understand the physics of our universe.
