Soft-unclustered-energy patterns from quirks / Curtin, David (Toronto U. ; CERN) ; Dreyer, Sascha (DESY) ; Fusté Costa, Max (DESY ; Hamburg U.) ; Heim, Sarah (DESY ; Hamburg U.) ; Kasieczka, Gregor (Hamburg U.) ; Moureaux, Louis (Hamburg U.) ; Rousso, David (DESY) ; Shih, David (Rutgers U., Piscataway) ; Sommerhalder, Manuel (Hamburg U.)
We propose searching for physics beyond the Standard Model in the low-transverse-momentum tracks accompanying hard-scatter events at the LHC. TeV-scale resonances connected to a dark QCD sector could be enhanced by selecting events with anomalies in the track distributions. [...]

Resonant Landau-Zener conversion in multi-axion systems / Dunsky, David I. (New York U., CCPP) ; Manzari, Claudio Andrea (UC, Berkeley ; LBL, Berkeley) ; Quílez, Pablo (UC, San Diego ; CERN) ; Ramos, Maria (CERN) ; Sørensen, Philip (U. Padua, Dept. Phys. Astron. ; INFN, Padua)
Multiple axions may emerge in the low-energy effective theory of Nature. Generically, the potentials describing these axion fields are non-diagonal, leading to mass mixing between axion states which can be temperature-dependent due to QCD instanton effects. [...]

Constellation: The autonomous control and data acquisition system for dynamic experimental setups / Spannagel, Simon (DESY) ; Lachnit, Stephan (DESY) ; Perrey, Hanno (ESS, Lund) ; Braach, Justus (CERN) ; Bryngemark, Lene Kristian (Lund U.) ; Garutti, Erika (Hamburg U.) ; Herkert, Adrian (DESY) ; King, Finn (DESY) ; Krieger, Christoph (Hamburg U.) ; Leppla-Weber, David (DESY) et al.
The operation of instruments and detectors in laboratory or beamline environments presents a complex challenge, requiring stable operation of multiple concurrent devices, often controlled by separate hardware and software solutions. These environments frequently undergo modifications, such as the inclusion of different auxiliary devices depending on the experiment or facility, adding further complexity. [...]

Simulation and experimental validation of atom effusion characteristics for resonance ionization laser ion source geometries / Jaradat, Asar A H (CERN ; U. Manchester (main)) ; Heinke, Reinhard (CERN ; U. Manchester (main)) ; Marsh, Bruce A (CERN) ; Studer, Dominik (Darmstadt, GSI ; Helmholtz Inst., Mainz) ; Lynch, Kara M (U.

Manchester (main)) ; Wendt, Klaus (Mainz U.) ; Stemmler, Matou (Mainz U.) ; Raeder, Sebastian (Darmstadt, GSI ; Helmholtz Inst., Mainz) ; Rothe, Sebastian (CERN) et al.
A Monte-Carlo-type simulation model has been developed to describe the effusion of atoms from hot cavity tubes for application to high-purity laser resonance ionization ion sources. The model is validated by comparison with theoretical descriptions of low-pressure particle transfer mechanisms and experimental data obtained by probing the spatial evolution of the atom density downstream for different atom source geometries with laser ionization.

Isospin mixing in Ga64,66 reexamined via total absorption spectroscopy / ISOLDE Collaboration
New measurements of the β decay of Ga64 and Ga66 have been carried out using total absorption spectroscopy at CERN-ISOLDE. The purpose of the study was to determine whether systemic effects such as Pandemonium have affected previous measurements and also determine the degree of isospin mixing in these proton-rich nuclei.

Direct Evidence for the νd5/2 Orbital in Ni69: Implications for the N=40 Island of Inversion / ISOLDE Collaboration
Shape coexistence, a collective manifestation of nuclear structure, emerges from the underlying single-particle dynamics and is prominently observed in the region below Ni68. Theoretical studies have emphasized the key role of the νd5/2 orbital, the quadrupole partner of νg9/2, in driving deformation. [...]

ALICE ITS3 MOSAIX stitched wafer-scale sensor – Implementation challenges and solutions / Lalic, Jelena (MIT) /ALICE Collaboration
MOSAIX is a full-scale, full-size monolithic CMOS pixel sensor prototype developed for the ALICE Inner Tracking System 3 (ITS3), which will replace the three innermost layers of the ALICE tracker during the LHC Long Shutdown 3 (LS3). With over 26 cm in length and 2 cm in width, MOSAIX contains 12 Repeated Sensor Units (RSUs). [...]

Bergen (main)) et al.
The ATLAS Inner Detector will be replaced by a new all-silicon Inner Tracker (ITk) in 2029 to meet the challenges of the High Luminosity LHC (HL-LHC). The ITk pixel system combines 3D sensors at the innermost layer, operating after exposure to fluences of up to 2 × 10$^{16}$ n$_{eq}$/cm$^{2}$, with thin n-in-p planar modules in the outer layers.

ALICE ITS2: Performance and Operational Experience / Kim, Jiyoung (CERN ; Inha U.) /ALICE Collaboration
The ALICE Inner Tracking System (ITS2) is the innermost tracking detector of the ALICE experiment, providing vertex reconstruction and tracking of charged particles. The upgraded detector consists of seven cylindrical layers of Monolithic Active Pixel Sensors covering 10 $m^2$ of active area and has been successfully operating since 2021.The ALPIDE sensors, manufactured using a 180 nm CMOS technology, feature $29\,\times\,27$ $\mu$m pixels with a spatial resolution of 5 $\mu$m.
