Production, quality assurance and quality control of the SiPM Tiles for the DarkSide-20k Time Projection Chamber

Fabio Acerbi, P. Adhikari, P. Agnes, I. Ahmad et autres

Abstract The DarkSide-20k dark matter direct detection experiment will employ a $${21}\,\hbox {m}^{2}$$ 21 m 2 silicon photomultiplier (SiPM) array, instrumenting a dual-phase 50 tonnes liquid argon Time Projection Chamber (TPC). SiPMs are arranged into modular photosensors called Tiles , each integrating …

Quality assurance and quality control of the $$26~\text {m}^2$$ SiPM production for the DarkSide-20k dark matter experiment

Fabio Acerbi, P. Adhikari, P. Agnes, I. Ahmad et autres

Abstract DarkSide-20k is a novel liquid argon dark matter detector currently under construction at the Laboratori Nazionali del Gran Sasso (LNGS) of the Istituto Nazionale di Fisica Nucleare (INFN) that will push the sensitivity for Weakly Interacting Massive Particle (WIMP) detection into …

DarkSide-20k sensitivity to light dark matter particles

Fabio Acerbi, P. Adhikari, P. Agnes, I. Ahmad et autres

The dual-phase liquid argon time projection chamber is presently one of the leading technologies to search for dark matter particles with masses below 10 GeV c−2. This was demonstrated by the DarkSide-50 experiment with approximately 50 kg of low-radioactivity liquid argon as …

A new hybrid gadolinium nanoparticles-loaded polymeric material for neutron detection in rare event searches

Fabio Acerbi, P. Adhikari, P. Agnes, I. Ahmad et autres

Abstract Experiments aimed at direct searches for WIMP dark matter require highly effective reduction of backgrounds and control of any residual radioactive contamination. In particular, neutrons interacting with atomic nuclei represent an important class of backgrounds due to the expected similarity of …

Constraints on directionality effect of nuclear recoils in a liquid argon time projection chamber

P. Agnes, Irshad Ahmad, S. Albergo, I. M. Albuquerque et autres

Abstract The direct search for dark matter in the form of weakly interacting massive particles (WIMP) is performed by detecting nuclear recoils produced in a target material from the WIMP elastic scattering. The experimental identification of the direction of the WIMP-induced nuclear …

Study of cosmogenic activation above ground for the DarkSide-20k experiment

A. Elersich, P. Agnes, I. Ahmad, S. Albergo et autres

The activation of materials due to exposure to cosmic rays may become an important background source for experiments investigating rare event phenomena. DarkSide-20k, currently under construction at the Laboratori Nazionali del Gran Sasso, is a direct detection experiment for galactic dark matter …

Sensitivity projections for a dual-phase argon TPC optimized for light dark matter searches through the ionization channel

P. Agnes, I. Ahmad, S. Albergo, I. F. M. Albuquerque et autres

Dark matter lighter than $10\text{ }\text{ }\mathrm{GeV}/{c}^{2}$ 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. Sensitivity to light dark …

Complex singularities in the quark propagator

IL (United States) Argonne National Lab., C. Roberts, M. Frank

The Dyson-Schwinger equation for the quark propagator is being studied in the rainbow approximation using a gluon propagator that incorporates asymptotic freedom and is an entire function. The gluon propagator has a number of parameters that may be varied in order to …

Electromagnetic nucleon form factors

IL (United States) Argonne National Lab., A. Bender, C. Roberts, M. Frank

The Dyson-Schwinger equation framework is employed to obtain expressions for the electromagnetic nucleon form factor. In generalized impulse approximation the form factor depends on the dressed quark propagator, the dressed quark-photon vertex, which is crucial to ensuring current conservation, and the nucleon …

Electromagnetic pion form factor

IL (United States) Argonne National Lab., C. Roberts

A phenomenological Dyson-Schwinger/Bethe-Salpeter equation approach to QCD, formalized in terms of a QCD-based model field theory, the Global Color-symmetry Model (GCM), was used to calculate the generalized impulse approximation contribution to the electromagnetic pion form factor at space-like q{sup 2} on the …
