We report on the search for dark matter weakly interacting massive particles (WIMPs) in mass range below $10\text{ }\text{ }\mathrm{GeV}/{\mathrm{c}}^{2}$, from analysis of entire dataset acquired with a low-radioactivity argon target by DarkSide-50 experiment at Laboratori Nazionali del Gran Sasso. The new benefits more accurate calibration detector response, improved background model, and better determination systematic uncertainties, allowing us to accurately model rate spectra down...
We present a search for dark matter particles with sub-GeV/c^{2} masses whose interactions have final state electrons using the DarkSide-50 experiment's (12 306±184) kg d low-radioactivity liquid argon exposure. By analyzing ionization signals, we exclude new parameter space matter-electron cross section σ[over ¯]_{e}, axioelectric coupling constant g_{Ae}, and photon kinetic mixing κ. also set first direct-detection constraints on angle |U_{e4}|^{2} keV/c^{2} sterile neutrinos.
Dark matter elastic scattering off nuclei can result in the excitation and ionization of recoiling atom through so-called Migdal effect. The energy deposition from electron adds to deposited by nuclear system allows for detection interactions sub-GeV/c^{2} mass dark matter. We present new constraints using dual-phase liquid argon time projection chamber DarkSide-50 experiment with an exposure (12 306±184) kg d. analysis is based on signal alone significantly enhances sensitivity DarkSide-50,...

DarkSide-50 has demonstrated the high potential of dual-phase liquid argon time projection chambers in exploring interactions WIMPs GeV/c$^2$ mass range. The technique, based on detection ionization signal amplified via electroluminescence gas phase, allows to explore recoil energies down sub-keV We report here measurement yield electronic recoils $\sim$180~eV$_{er}$, exploiting $^{37}$Ar and $^{39}$Ar decays, extrapolated a few electrons with Thomas-Imel box model. Moreover, we present...

Abstract The stability of a dark matter detector on the timescale few years is key requirement due to large exposure needed achieve competitive sensitivity. It especially crucial enable potentially detect any annual event rate modulation, an expected signature. In this work, we present performance history DarkSide-50 dual-phase argon time projection chamber over its almost three-year low-radioactivity run. particular, focus electroluminescence signal that enables sensitivity sub-keV energy...
Abstract We present a novel approach for the search of dark matter in DarkSide-50 experiment, relying on Bayesian Networks. This method incorporates detector response model into likelihood function, explicitly maintaining connection with quantity interest. No assumptions about linearity problem or shape probability distribution functions are required, and there is no need to morph signal background spectra as function nuisance parameters. By expressing terms Networks, we have developed an...
Dark matter may induce an event in Earth-based detector, and its rate is predicted to show annual modulation as a result of the Earth’s orbital motion around Sun. We searched for this signature using ionization signal DarkSide-50 liquid argon time projection chamber.

We present 3D calculations for dielectric haloscopes such as the currently envisioned MADMAX experiment. For ideal systems with perfectly flat, parallel and isotropic disks of finite diameter, we find that a geometrical form factor reduces emitted power by up to $30\,\%$ compared earlier 1D calculations. derive beam shape, which is important antenna design. show realistic dark matter axion velocities $10^{-3} c$ inhomogeneities external magnetic field at scale $10\,\%$ have negligible impact...
Dark matter induced event rate in an Earth-based detector is predicted to show annual modulation as a result of the Earth's orbital motion around Sun. We searched for this signature using ionization signal DarkSide-50 liquid argon time projection chamber. No significant compatible with dark observed electron recoil equivalent energy range above $40~{\rm eV_{ee}}$, lowest threshold ever achieved such search.
