Magnetic monopoles remain a highly motivated yet experimentally elusive exotic particle. Point-like Dirac monopoles, along with other High-Electric-Charge Objects, could be produced in proton-proton collisions at the Large Hadron Collider and would generate a characteristic highly ionizing signature within the ATLAS detector. Building on a previous Run 2 analysis, I will present plans for a...

In a $U(1)_{R-L}$-symmetric supersymmetric model, pseudo-Dirac bino and wino can act like right-handed neutrinos, generating the light neutrino masses through a hybrid Type I + III inverse seesaw mechanism. We investigate such a model to accommodate the baryon asymmetry of the universe together with neutrino masses. A pseudo-Dirac gaugino goes under particle-antiparticle oscillations. ...

The ATLAS detector, located at the CERN laboratory, measures the products of high energy proton-proton and heavy-ion collisions produced by the Large Hadron Collider (LHC). Given the high collision energy of 13.6 TeV produced by the LHC, the ATLAS detector is a prime location to study fundamental interactions of the universe. To help search for these phenomena, the ATLAS Collaboration uses a...

926. Measurement of the Pion QCD Form Factor in e+e−→π+π− at sqrt(s)=10.58 GeV with the Belle II Detector

The pion QCD form factor encodes the effects of the strong interaction in processes involving pions and provides a fundamental probe of non-perturbative and asymptotic Quantum Chromodynamics (QCD).

Because first-principles calculations of non-trivial QCD interactions are challenging, empirically measured form factors play a crucial role in data-driven approaches. In particular, they can be...

665. Searching for soft unclustered energy patterns with the ATLAS detector

Soft Unclustered Energy Patterns (SUEPs) are an unconventional signature that can arise in hidden-sector models with approximately conformal dynamics. Unlike traditional new physics signals, SUEP events are dominated by high particle multiplicities, low individual transverse momenta, and nearly isotropic energy flow, making them challenging to identify using standard reconstruction and...
