This talk will discuss recent results from the ATLAS experiment concerning measurements in the electroweak and QCD sector. The highlighted topics include precision measurements of Drell-Yan and multiboson processes (including vector-boson-scattering), differential measurements of vector boson plus jets and multijets, novel study of jet substructures, probe of soft QCD phenomena, and precision...

The dual-radiator (dRICH) detector in the ePIC experiment at the upcoming Electron-Ion
Go to contribution page
Collider (EIC) will make use of SiPM sensors to detect the emitted Cherenkov light. The
photodetector will cover an area of approximately 3 mยฒ with 3ร3 mmยฒ pixels, for a total of more
than 300,000 readout channels. This will represent the Jirst use of SiPMs for single-photon
detection in a collider... -

The Electromagnetic Calorimeter (ECAL) of the CMS experiment at the LHC plays a vital role in various physics analyses, including Higgs boson studies and searches for new phenomena. Achieving accurate calibration of the detector and its individual channels is critical for optimizing the energy resolution of electrons and photons, as well as for measuring the electromagnetic components of jets...

Our presentation will include the observation of a rare beta decay of the charmed baryon $\Lambda_c^+ \to n e^+ \nu$ with a Graph Neural Network and the first measurement of the decay asymmetry in the pure... -
Dr Meike Kรผรner (Ruhr-Universitรคt Bochum)High Energy Particle PhysicsTalk
Although mesons have been known for decades, many questions about their nature remain unresolved. Beyond the conventional meson nonets, numerous candidates have been observed that may possess exotic structures, such as glueballs, hybrids, or tetraquarks. These states are particularly accessible in clean, gluon-rich environments.
