Experiment

In this talk, I will review recent highlights from the CMS experiment, including results from the HEPHY CMS Data Analysis group.

56. ALICE 3: A next generation heavy-ion detector

Jesper Karlsson Gumprecht (Austrian Academy of Sciences (AT))

11/02/2025, 09:05

Experiment

The 'ALICE 3' project is a proposed upgrade of the ALICE detector, which involves a complete replacement of the installation at Point 2 to fully utilize the high-luminosity LHC. Crucial to the physics programme are high-precision measurements of heavy-flavour observables that require large data samples as well as state-of-the-art tracking performance. As a consequence, performance studies of...

53. Overview of TU Wien Activities at the MedAustron Accelerator Facility

Matthias Kausel (MedAustron, TU Wien)

11/02/2025, 09:25

This presentation provides an overview of TU Wien's research activities at the MedAustron synchrotron in the fields of accelerator and medical physics, using the for research available 60-800 MeV proton, 120-400 MeV/u carbon and 40-400 MeV/u helium ion beams.
These activities include, among others, the delivery of novel ion beam modalities, such as ultra-low flux and mixed helium-carbon ion...

60. The n_TOF experiment - neutrons for nuclear technology, medicine & fundamental research

Michael Bacak (Vienna University of Technology (AT))

11/02/2025, 09:45

Experiment

The pulsed broad-range neutron time-of-flight facility n_TOF at CERN is a world-leading research facility for studying neutron-induced reactions. The CERN accelerator complex’ high intensity short proton pulses impinge on a a massive gas cooled lead spallation target. The resulting high instantaneous intensity neutron pulses arrive at two experiment stations EAR1 and EAR2, at 185 m and 19 m...

61. Silicon Carbide Detectors for Future Colliders and Medical Applications

Andreas Gsponer (Austrian Academy of Sciences (AT))

11/02/2025, 10:05

Experiment

Silicon carbide (SiC), a wide bandgap semiconductor, has many excellent material properties that make it an attractive candidate for particle detectors. Thanks to widespread usage in the power electronics industry, SiC processing has undergone significant quality improvements in the last ten years, with a reduction in price and an increase in wafer sizes. At the same time, particle physics...

58. COSINUS and CRESST updates

Philipp Schreiner (Vienna University of Technology (AT))

11/02/2025, 10:25

Experiment

COSINUS (Cryogenic Observatory for SIgnatures seen in Next-generation Underground Searches) and CRESST (Cryogenic Rare Event Search with Superconducting Thermometers) are experiments conducted at the LNGS (Laboratori Nazionali del Gran Sasso) in Italy. Both search for dark matter (DM) nucleus scattering, and their key technology is a combination of 1) using transition edge sensors (TESs) on...

54. Particle physics at the University of Graz

Michael Mandl (University of Graz)

Theory

I will give a brief overview of the research activities currently going on in the field of particle physics at the University of Graz.

55. Ongoing research at the University of Vienna

Prof. Massimiliano Procura (University of Vienna)

11/02/2025, 11:35

I will provide a concise overview of the current research being conducted by the particle physics group at the University of Vienna.

57. Machine learning in lattice QCD and beyond

Andreas Ipp (TU Wien)

11/02/2025, 11:55

Theory

I will give an overview of our group’s progress in applying machine learning to lattice QCD, including the design of gauge-equivariant neural network layers that can learn a fixed-point action. I will also share our ongoing work on diffusion models and ideas for collaborative efforts towards large physics models.

I would like to take this chance to promote the European Coalition for AI in...

52. Tensor mesons in holographic QCD and their contribution to the muon g-2

Jonas Mager (TU Wien)

11/02/2025, 12:15

Theory

The hadronic light-by-light contribution to the muon $g-2$ contains contributions from intermediate massive spin 2 particles, i.e. tensor mesons.

We use holographic models of QCD (hQCD) to calculate masses, decay constants and transition form factors (TFFs) of tensor mesons and compare them to experimental data. These tensor meson TFFs may be decomposed into 5 Lorentz structures $T_i^{\mu...

51. Conclusions not yet drawn from the unsolved 4/3-problem.\\ How to get a stable classical electron.

Manfried Faber

11/02/2025, 12:35

Theory

It has been known for over 100 years that there is a discrepancy between Maxwell's electrodynamics and the idea of a classical electron as the ``atom'' of electricity. This incompatibility is known under the terms 4/3 problem of the classical electron and radiation reaction force and was circumvented in the currently most successful theories, the quantum field theories, by limit value...
