The Strong Interaction at 50 Years: less Puzzling, more Rich, and still Mysterious / Stewart, Iain (speaker)
The strong interaction is described by a remarkable theory called Quantum Chromodynamics (QCD), a quantum field theory that is fully consistent at all distance scales and that gives rise to interesting emergent phenomena.  It plays a crucial role in a variety of important physical processes, from binding together quarks and gluons in the proton, to the evolution of a hot-plasma of matter in the early universe, to producing streams of collimated particles called jets in high energy collisions.  In this talk I will review what we have learned about QCD and its phenomena in the fifty years since its inception, as well as discussing the important role that control of QCD effects have on measuring the fundamental parameters of the standard model of particle and nuclear physics.  To highlight the mysteries of QCD that remain unsolved, I will describe a top-10 list of important open questions. This seminar is part of the conference "Parton Showers and Resummation" (https://indico.cern.ch/event/1487647)

Where sample statistics matter: ATLAS improves searches for rare Higgs boson decays with the large Run 3 data set / Liu, Kun (speaker) (Tsung-Dao Lee Institute, Shanghai Jiao Tong University)
The decays of the Higgs boson into rare decay channels like H→Zγ→ℓℓγ and H→μμ are very challenging due to their small branching ratios and large backgrounds. The first decay, H→Zγ→ℓℓγ, is sensitive to potential BSM effects since SM contributions are loop-suppressed [...]

Searching for Sub-GeV Dark Matter (TH BSM institute) / Dolan, Matthew (speaker) (University of Melbourne)
Direct detection of sub-GeV mass dark matter which scatters off nuclei has long been challenging due to loss of experimental sensitivity in this region of parameter space. However, sensitivity can be regained by exploiting the Migdal effect: the ionisation or excitation of atomic electrons after a nuclear scattering event [...]

Examining the nucleosynthesis process and the inner nuclei structure with (anti)hypernuclei with ALICE at the LHC / Ditzel, Janik (speaker) (Goethe University Frankfurt (DE))
Hypernuclei are bound states of nucleons and hyperons. The measurement of the production of hypernuclei with mass number A=3 and 4 in heavy-ion colli- sions is a powerful tool to investigate the mechanism of the nucleosynthesis [...]

Cryogenic Readout Electronics / Charbon, Edoardo (speaker) (EPFL)
The core of a quantum computer or a quantum sensor is generally an array of qubits or quantum detectors and classical electronics for its control; it operates on the qubits/detectors with nanosecond latency and a very low noise. Classical electronics is generally operating at room temperature, however recently, we have proposed that it moves closer to the qubits/detectors and operates at cryogenic temperatures to improve compactness and reliability [...]

Pushing the Limits: Advanced SiC Detectors for Operation in Harsh Environments / Pellegrini, Giulio (speaker) (Centro Nacional de Microelectrónica (IMB-CNM-CSIC) (ES))
Silicon carbide (SiC) detectors are emerging as key components for radiation monitoring in extreme environments, including ultra-high dose rate (UHDR) FLASH radiotherapy, nuclear physics, high energy physics and  plasma diagnostic in fusion reactors. This talk will present the technological development and characterization of SiC p–n diodes for UHDR dosimetry and neutron detection [...]

Superradiant Interactions of Cosmic Relics (TH BSM institute) / Dimopoulos, Savas (speaker) (Stanford University)
In this talk, I will describe three things. First, I will outline the conditions under which the interaction rate of inelastic processes that change the internal state of a system of N targets scales N^2. This is an effect distinct from coherent elastic scattering, but with the same scaling [...]

Cornering natural supersymmetry using ultra-soft signatures at CMS / Bein, Samuel Louis (speaker) (Universite Catholique de Louvain (UCL) (BE))
Results from the CMS experiment are presented for natural supersymmetry (SUSY) targeting so-called compressed scenarios, namely models with very small mass differences among the SUSY partners. Such models pose unique experimental challenges, including for triggering, offline selection, and background treatment [...]
