27. ATLAS results on Higgs Physics and Electroweak Symmetry Breaking

Flera Rizatdinova (Oklahoma State University (US))

9/16/25, 3:00 PM

This talk presents recent precision measurements of key properties of the Higgs boson using the full dataset of proton-proton collisions at √s = 13 TeV and 13.6 teV collected during Run 2 and Run 3, respectively, of the LHC by the ATLAS experiment. Highlights on Higgs cross sections, couplings and di-Higgs searches will be discussed.

46. Critical Phenomena in Hadronic and DIS Processes

Prof. CARLOS MERINO

9/16/25, 3:35 PM

We compare the critical phenomena (e.g. phase transitions, crossover) in proton-proton, proton-nucleus scattering and in lepton-proton deep inelastic scattering (DIS) systems.

59. Stress-energy tensor in bound states

Andrzej Czarnecki

9/16/25, 4:40 PM

In this talk, we re-examine the recent claim that a Dirac particle freely falling in a uniform gravitational field exhibits a spin-dependent transverse deflection (gravitational spin Hall effect). Using a circulating-mass model, we show that an object with angular momentum carries a hidden momentum, which leads to a mismatch of the conventional relation between the canonical momentum and the...

30. Highlights of the ATLAS detector upgrade

Alexander Cheplakov

The High-Luminosity LHC (HL-LHC) physics programme will be critical to deepening our understanding of fundamental physics, enabling us to probe the Standard Model with extreme precision and search for new physics using a vast array of data.
Achieving these goals under HL-LHC environment requires unprecedented detector technologies in terms of radiation hardness, high detection granularity and...

19. ATLAS Tile Calorimeter Phase-II Upgrade: current status and electronics certification with Portable Readout Module ”PROMETEO”

Pavle Tsotskolauri (Ivane Javakhishvili Tbilisi State University (GE))

9/16/25, 5:40 PM

The High-Luminosity LHC (HL-LHC) will extend the physics reach of the ATLAS experiment, bringing new opportunities for discovery and measuring the properties of particles. To achieve this, the HL-LHC requires a complete upgrade of the ATLAS detector, including its Tile Calorimeter (TileCal). TileCal is a sampling hadronic calorimeter covering the central region of the ATLAS experiment in a...
