The $\pi^+\pi^-$ Coulomb interaction study and its use in the data processing / Adeva, B. (Santiago de Compostela U.) ; Afanasyev, L. (Dubna, JINR) ; Anania, A. (INFN, Messina) ; Aogaki, S.

In this work the Coulomb effects (Coulomb correlations) were studied using experimental $\pi^+\pi^-$ pair distributions in $Q$, the relative momentum in the pair center of mass system (c.m.s), and its projections $Q_L$ (longitudinal component) and $Q_t$ (transverse component) relative to the pair direction in the laboratory system (l.s.). The major part of the pion pairs is produced by decay of $\rho, \omega$ and $\Delta$ and other short-lived sources (Coulomb pairs). [...]

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. [...]

Investigation of $K^+K^-$ pairs in the effective mass region near $2m_K$ / DIRAC Collaboration
The DIRAC experiment at CERN investigated in the reaction $\rm{p}(24~\rm{GeV}/c) + Ni$ the particle pairs $K^+K^-, \pi^+ \pi^-$ and $p \bar{p}$ with relative momentum $Q$ in the pair system less than 100 MeV/c. Because of background influence studies, DIRAC explored three subsamples of $K^+K^-$ pairs, obtained by subtracting -- using time-of-flight (TOF) technique -- background from initial $Q$ distributions with $K^+K^-$ sample fractions more than 70%, 50% and 30%.

A new aerogel Cherenkov detector for DIRAC-II / Allkofer, Y (Zurich U.) ; Amsler, Claude (Zurich U.) ; Horikawa, S (Zurich U.) ; Regenfus, Christian (Zurich U.) ; Rochet, J (Zurich U.)
A new threshold Cherenkov detector using silica aerogel radiators is in operation in the DIRAC-II experiment at CERN. A duplex design was chosen to discriminate between kaons and protons in the momentum range 4-8 GeV/ c . [...]

Performance study of a $3\times1\times1$ m$^3$ dual phase liquid Argon Time Projection Chamber exposed to cosmic rays / WA105 Collaboration
We report the results of the analyses of the cosmic ray data collected with a 4 tonne (3$\times$1$\times$1~m$^3$) active mass (volume) Liquid Argon Time-Projection Chamber (TPC) operated in a dual-phase mode. We present a detailed study of the TPC's response, its main detector parameters and performance. [...]

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.

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. [...]
