“…The overall excluded region in the case of COHERENT is relatively weaker for the current COHERENT data compared to the other experiments but competitive with KATRIN, at least in the case of NH. However, more data in the future from COHERENT and other similar experiments CEνNS experiments can certainly improve these limits [91,108,121,[134][135][136][137][138][139][140][141][142][143][144].…”

“…Regarding the CEνNS, we have focused on the real data collected by the COHERENT experiment. However, future experiments with accelerator and reactor neutrinos can also test the extra dimensions using the different frameworks presented here [91,108,121,[134][135][136][137][138][139][140][141][142][143][144]. Moreover, since the size of the 4D mass of the heavy right-handed neutrinos is restricted only by the energy of the incoming neutrinos, an interesting application of this framework would be to the high energy facilities, for example, LHC [63], FASER [64], MATSULA [65], ShiP [66,67], Bell II [68], FCC [69].…”

We explore the possibility of relating extra dimensions with light and heavy Dirac-type neutral leptons and develop a framework for testing them in various laboratory experiments. The Kaluza-Klein modes in the large extra dimension models of the light neutral leptons could mix with the standard model neutrinos and produce observable effects in the oscillation experiments. We show that the chirality flipping up-scattering processes occurring through either neutrino magnetic dipole moment or the weakly coupled scalar interactions can also produce heavy Kaluza-Klein modes of the corresponding right-handed neutral leptons propagating in one or more extra dimensions. However, to conserve the four- dimensional energy-momentum, their masses must be below the maximum energy of the neutrinos in the initial state. The appreciable size of extra dimensions connected with these heavy neutral leptons can thus affect the cross-sections of these processes. This framework applies to any up-scattering process. Our work here focuses only on its application to the coherent elastic neutrino-nucleus scattering process. We derive constraints on the size of extra dimensions using the COHERENT data in oscillation and up-scattering processes. For model with one large extra dimension for the light neutral leptons, we obtain the limits, R ~ 3 μm (NH) and R ~ 2.5 μm (IH), on the size of extra dimension corresponding to the absolute mass limit, m0 ≤ 3 × 10−3 eV at 90% C.L. from the short-baseline oscillations. Using the up-scattering process for heavy neutral leptons, we obtain new parameter spaces between the size of extra dimensions and parameters of the dipole or scalar interactions.

“…More recently, a suggestive evidence for CEνNS from reactor antineutrinos was reported by the Dresden-II Collaboration [10]. Moreover, several reactor-based CEνNS experiments aim at measuring this process, such as: CONNIE [11], CONUS [12], νGEN [13], MINER [14], RICOCHET [15], ν-cleus [16], TEXONO [17], vIOLETA [18] and Scintillating Bubble Chamber (SBC) [19]. There are also further experimental efforts underway, aiming to use π-DAR at the European Spallation Source [20] and at the LANSCE Lujan Center [21].…”

The observation of coherent elastic neutrino nucleus scattering has opened the window to many physics opportunities. This process has been measured by the COHERENT Collaboration using two different targets, first CsI and then argon. Recently, the COHERENT Collaboration has updated the CsI data analysis with a higher statistics and an improved understanding of systematics. Here we perform a detailed statistical analysis of the full CsI data and combine it with the previous argon result. We discuss a vast array of implications, from tests of the Standard Model to new physics probes. In our analyses we take into account experimental uncertainties associated to the efficiency as well as the timing distribution of neutrino fluxes, making our results rather robust. In particular, we update previous measurements of the weak mixing angle and the neutron root mean square charge radius for CsI and argon. We also update the constraints on new physics scenarios including neutrino nonstandard interactions and the most general case of neutrino generalized interactions, as well as the possibility of light mediators. Finally, constraints on neutrino electromagnetic properties are also examined, including the conversion to sterile neutrino states. In many cases, the inclusion of the recent CsI data leads to a dramatic improvement of bounds.

“…Relatively highenergy neutrinos with significant background reduction using the timing information of the pulsed beam had allowed the capture of a low-energy signal induced by the CEνNS process [20,21]. However, such success has not been achieved using other neutrino sources, such as reactors [19,[24][25][26] or solar neutrinos [27], although extensive efforts have been made. In particular, reactor neutrinos with energy reaching a few MeV produce visible recoils with energy less than 1 keV, which is significantly lower than the typical energy threshold of a kg-size particle detector.…”

Exploring coherent elastic neutrino-nucleus scattering using reactor electron antineutrinos in the NEON experiment

et al. 2023

Neutrino elastic scattering observation with NaI (NEON) is an experiment designed to detect neutrino-nucleus coherent scattering using reactor electron antineutrinos. NEON is based on an array of six NaI(Tl) crystals with a total mass of 13.3 kg, located at the tendon gallery that is 23.7 m away from a reactor core with a thermal power of 2.8 GW in the Hanbit nuclear power complex. The installation of the NEON detector was completed in December 2020, and since May 2021, the detector has acquired data at full reactor power. Based on the observed light yields of the NaI crystals of approximately 22, number of photoelectrons per unit keV electron-equivalent energy (keVee), and 6 counts/kg/keV/day background level at 2–6 keVee energy, coherent elastic neutrino-nucleus scattering (CE$$\nu $$ ν NS) observation sensitivity is evaluated as more than 3$$\sigma $$ σ assuming 1-year reactor-on and 100 days reactor-off data, 0.2 keVee energy threshold, and 7 counts/keV/kg/day background in the signal region of 0.2$$-$$ - 0.5 keVee. This paper describes the design of the NEON detector, including the shielding arrangement, configuration of NaI(Tl) crystals, and associated operating systems. The initial performance and associated sensitivity of the experiment are also presented.
