Sensitivity projections for a dual-phase argon TPC optimized for light dark matter searches through the ionization channel / Global Argon Dark Matter Collaboration
Dark matter lighter than 10 GeV/c$^2$ encompasses a promising range of candidates. A conceptual design for a new detector, DarkSide-LowMass, is presented, based on the DarkSide-50 detector and progress toward DarkSide-20k, optimized for a low-threshold electron-counting measurement. [...]

Considerations for the VELO detector at the LHCb Upgrade II / Akiba, Kazu (Nikhef National institute for subatomic physics (NL)) ; Alexander, Michael Thomas (University of Glasgow (GB)) ; Back, John James (University of Warwick (GB)) ; Bates, Richard (University of Glasgow (GB)) ; Bertella, Claudia (University of Manchester (GB)) ; Van Beuzekom, Martin (Nikhef National institute for subatomic physics (NL)) ; Seman Bobulska, Dana (University of Glasgow (GB)) ; Boente Garcia, Oscar (Universidade de Santiago de Compostela (ES)) ; Bogdanova, Galina (M.V. Lomonosov Moscow State University (RU)) ; Borghi, Silvia (University of Manchester (GB)) et al.
The LHCb experiment is planning to operate with a 7.5-fold increase in instantaneous luminosity for LHC Runs 5 and 6. The performance of the Vertex Locator detector is crucial in the event reconstruction at the increased pile-up, providing real-time information to be used in the trigger. [...]

Separating $^{39}$Ar from $^{40}$Ar by cryogenic distillation with Aria for dark matter searches / DarkSide Collaboration
The Aria project consists of a plant, hosting a 350 m cryogenic isotopic distillation column, the tallest ever built, which is currently in the installation phase in a mine shaft at Carbosulcis S.p.A., Nuraxi-Figus (SU), Italy. Aria is one of the pillars of the argon dark-matter search experimental program, lead by the Global Argon Dark Matter Collaboration. [...]

Sensitivity of future liquid argon dark matter search experiments to core-collapse supernova neutrinos / DarkSide 20k Collaboration
Future liquid-argon DarkSide-20k and ARGO detectors, designed for direct dark matter search, will be sensitive also to core-collapse supernova neutrinos, via coherent elastic neutrino-nucleus scattering. This interaction channel is flavor-insensitive with a high-cross section, enabling for a high-statistics neutrino detection with target masses of $\sim$50~t and $\sim$360~t for DarkSide-20k and ARGO, respectively. [...]

Competition between Allowed and First-Forbidden $β$ Decay: The Case of $^{208}$Hg$→^{208}$Tl / Carroll, R J (Surrey U.) ; Podolyák, Zs (Surrey U. ; Darmstadt, GSI) ; Berry, T (Surrey U.) ; Grawe, H (Darmstadt, GSI) ; Alexander, T (Surrey U.) ; Andreyev, A N (York U., England ; JAEA, Ibaraki) ; Ansari, S (Cologne U.) ; Borge, M J G (CERN) ; Brunet, M (Surrey U.) ; Creswell, J R (Liverpool U.) et al.
The $β$ decay of $^{208}$Hg into the one-proton hole, one neutron-particle $^{208}_{81}$Tl$_{127}$ nucleus was investigated at CERN-ISOLDE. Shell-model calculations describe well the level scheme deduced, validating the proton-neutron interactions used, with implications for the whole of the N>126, Z<82 quadrant of neutron-rich nuclei.

Octupole states in $^{207}$Tl studied through $β$ decay / Berry, T A (Surrey U.) ; Podolyák, Zs (Surrey U.) ; Carroll, R J (Surrey U.) ; Lică, R (CERN ; Bucharest, IFIN-HH) ; Brown, B A (Michigan State U.) ; Grawe, H (Darmstadt, GSI) ; Sotty, Ch (Bucharest, IFIN-HH ; Leuven U.) ; Timofeyuk, N K (Surrey U.) ; Alexander, T (Surrey U.) ; Andreyev, A N (York U., England) et al.
The $β$ decay of $^{207}$Hg into the single-proton-hole nucleus $^{207}$Tl has been studied through $γ$-ray spectroscopy at the ISOLDE Decay Station (IDS) with the aim of identifying states resulting from coupling of the $πs^{−1}_{1/2}, πd^{−1}_{3/2},$ and $πh^{−1}_{11/2}$ shell model orbitals to the collective octupole vibration. Twenty-two states were observed lying between 2.6 and 4.0 MeV, eleven of which were observed for the first time, and 78 new transitions were placed. [...]

SiPM-matrix readout of two-phase argon detectors using electroluminescence in the visible and near infrared range / DarkSide Collaboration
Proportional electroluminescence (EL) in noble gases is used in two-phase detectors for dark matter searches to record (in the gas phase) the ionization signal induced by particle scattering in the liquid phase. The "standard" EL mechanism is considered to be due to noble gas excimer emission in the vacuum ultraviolet (VUV). [...]

Design and construction of a new detector to measure ultra-low radioactive-isotope contamination of argon / DarkSide Collaboration
Large liquid argon detectors offer one of the best avenues for the detection of galactic weakly interacting massive particles (WIMPs) via their scattering on atomic nuclei. The liquid argon target allows exquisite discrimination between nuclear and electron recoil signals via pulse-shape discrimination of the scintillation signals. [...]

Investigation of the $\Delta n = 0$ selection rule in Gamow-Teller transitions: The $\beta$-decay of $^{207}$Hg / Berry, T A (Surrey U.) ; Podolyák, Zs (Surrey U.) ; Carroll, R J (Surrey U.) ; Lică, R (CERN ; Bucharest, IFIN-HH) ; Grawe, H ; Timofeyuk, N K (Surrey U.) ; Alexander, T (Surrey U.) ; Andreyev, A N (York U., England) ; Ansari, S (Cologne U.) ; Borge, M J G (CERN ; Madrid, Inst. Estructura Materia) et al.
Gamow-Teller $\beta$ decay is forbidden if the number of nodes in the radial wave functions of the initial and final states is different. This $\Delta n=0$ requirement plays a major role in the $\beta$ decay of heavy neutron-rich nuclei, affecting the nucleosynthesis through the increased half-lives of nuclei on the astrophysical $r$-process pathway below both $Z=50$ (for $N>82$ ) and $Z=82$ (for $N>126$).
