“…An extensivelystudied scenario of new physics of neutrinos is the socalled non-standard interaction (NSI) [817], which might play a potentially important role in future long-baseline experiments such as DUNE [818]. In addition, there has also been rising interest in new interactions mediated by light mediators [819][820][821][822]. A next-generation liquid xenon detector can significantly improve the sensitivity to sterile neutrino mixing parameters, particularly if solar neutrino detection via elastic neutrino-electron scattering (pp component) and the CEνNS channel ( 8 B component) is combined with reactor neutrino data from JUNO [823].…”

The nature of dark matter and properties of neutrinos are among the most pressing issues in contemporary particle physics. The dual-phase xenon time-projection chamber is the leading technology to cover the available parameter space for Weakly Interacting Massive Particles (WIMPs), while featuring extensive sensitivity to many alternative dark matter candidates. These detectors can also study neutrinos through neutrinoless double-beta decay and through a variety of astrophysical

“…With the "discovery" phase behind our backs, we must now turn to a "precision" phase, aiming at increasing the statistics and precision of the measurements. To this end, various proposals have been put forward [10][11][12]. The aim is to fully develop the CEνNS physics case and overcome the experimental difficulty of detecting very small nuclear recoil energies.…”

Future experiments dedicated to the detection of Coherent Elastic Neutrino-Nucleus Scattering may be powerful tools in probing light new physics. In this paper we study the sensitivity on light Z′ mediators of two proposed experiments: a directional low pressure Time Projection Chamber detector, νBDX-DRIFT, that will utilize neutrinos produced at the Long Baseline Neutrino Facility, and several possible experiments to be installed at the European Spallation Source. We compare the results obtained with existing limits from fixed-target, accelerator, solar neutrino and reactor experiments. Furthermore, we show that these experiments have the potential to test unexplored regions that, in some case, could explain the anomalous magnetic moment of the muon or peculiar spectral features in the cosmic neutrino spectrum observed by IceCube.

“…The computations depend sensitively on the particular detector details, so for concreteness we focus on the SENSEI detector located at Fermilab near the MINOS cavern and the data presented in [11]. However, the methods that we present can be adapted to other existing and proposed DM and neutrino detectors, including SENSEI at SNOLAB, DAMIC, DAMIC-M, Oscura [19][20][21], CONNIE [22], νIOLETA [23], DarkNESS [24], and CCDs used in astronomy [25].…”

The reach of sub-GeV dark-matter detectors is at present severely affected by low-energy events from various origins. We present the theoretical methods to compute the single-and few-electron events that arise from secondary radiation emitted by highenergy particles as they pass through detector materials and perform a detailed simulation to quantify them at (Skipper) CCD-based experiments, focusing on the SENSEI data collected at Fermilab near the MINOS cavern. The simulations account for the generation of secondaries from Cherenkov and luminescent recombination radiation; photo-absorption in the bulk, backside layer, pitch adapter, and epoxy; the photon reflection and refraction at interfaces; thin-film interference; the roughness of the interfaces; the dynamics of charges produced in the highly doped CCD-backside-layers; and the partial charge collection on the CCD backside. We consider several systematic uncertainties, notably those stemming from the backside modeling, which we estimate with a "fiducial" and an "extreme" charge-diffusion model, with the former model being preferred due to better agreement with partial-charge collection data. We find that Cherenkov photons constitute about 40% of the observed single-electron events for both diffusion models; radiative recombination contributes negligibly to the event rate for the fiducial model, although it can dominate over Cherenkov for the extreme model. We also estimate the fraction of 2-electron events that arise from 1-electron event coincidences in the same pixel, finding that the entire 2-electron rate can be explained by coincidences of radiative events and spurious charge. Accounting for both radiative and non-radiative backgrounds, we project the sensitivity of future Skipper-CCD-based experiments to different dark-matter models. For light-mediator models with dark-matter masses of 1, 5, and 10 MeV, we find that future experiments with 10-kg-year exposures and successful background mitigation could have a sensitivity that is larger by 9, 3, and 2 orders of magnitude, respectively, when compared to an experiment without background improvements.
