“…A favored hypothesis that explains these observations is that dark matter is made of Weakly Interacting Massive Particles (WIMPs). A great effort is then currently devoted to find some evidence of these new particles [1][2][3][4]. Direct dark matter search experiments look for an excess of signals in an underground, low background environment; different detectors have been built for this purpose, with the aim to measure small energy depositions (1÷100 keV).…”

A: DarkSide is a staged experimental project based on radiopure argon aiming at direct dark matter detection. The DarkSide-50 (DS-50) detector is currently operating underground at the Gran Sasso National Laboratory. DS-50 detector is a dual-phase, 50 kg, liquid argon timeprojection-chamber readout by 38 cryogenic PMTs (Hamamatsu R11065), surrounded by an active liquid scintillator veto and contained in a water Cherenkov detector acting as a muon veto. DS-50 has been been operating continuously since 2013, first with atmospheric argon and subsequently filled in 2015 with argon from an underground source, allowing a reduction of the 39 Ar isotope by more than a factor 1000. Features of the DS-50 detector are described, long term operations and stability are reported and its performances in scintillation light detection discussed. Results on dark matter searches obtained with DarkSide-50 detector are briefly reported.

“…It has been well tested by a variety of experiments, and all the fundamental particles it predicts have been found. However, the SM cannot explain the existence of cold dark matter (DM) in the Universe, which is strongly suggested by astrophysical and cosmological experiments [4][5][6]. In order to account for particle dark matter, the SM must be extended.…”

We study a dark matter model constructed by extending the standard model with an inert SU(2)L sextuplet scalar of hypercharge 1/2. The sextuplet components are split by the quartic couplings between the sextuplet and the Higgs doublet after electroweak symmetry breaking, resulting in a dark sector with one triply charged, two doubly charged, two singly charged, and two neutral scalars. The lighter neutral scalar boson acts as a dark matter particle. We investigate the constraints on this model from the monojet + "Image missing" and soft-dilepton + jets + "Image missing" searches at the 13 TeV Large Hadron Collider, as well as from the current electroweak precision test. Furthermore, we estimate the projected sensitivities of a 100 TeV pp collider and of a future e+e− collider, and find that such future projects could probe TeV mass scales. Nonetheless, such mass scales only correspond to a subdominant component of the observed relic abundance if the dark matter particles solely originate from thermal production.

“…Introduction.-Extensive cosmological and astrophysical observations at different scales provide compelling evidence on the existence of missing matter in the Universe [1]. This motivates intense efforts to study extensions to the standard model (SM) [2].…”

We report constraints on the dark photon effective kinetic mixing parameter (κ) with data taken from two p-type point-contact germanium detectors of the CDEX-10 experiment at the China Jinping Underground Laboratory. The 90% confidence level upper limits on κ of solar dark photon from 205.4 kg-day exposure are derived, probing new parameter space with masses (m V) from 10 to 300 eV=c 2 in direct detection experiments. Considering dark photon as the cosmological dark matter, limits at 90% confidence level with m V from 0.1 to 4.0 keV=c 2 are set from 449.6 kg-day data, with a minimum of κ ¼ 1.3 × 10 −15 at m V ¼ 200 eV=c 2 .
