CONUS+ is an experiment installed at the Leibstadt nuclear power plant (KKL), Switzerland, at 20.7 m from the 3.6 GW core, operating four point-contact HPGe detectors (3.74 kg total, ~160 eVee threshold). It has recently achieved the first detection of CEνNS of reactor antineutrinos on germanium nuclei in the fully coherent regime.

The NUCLEUS experiment aims to detect Coherent Elastic Neutrino-Nucleus Scattering (CEvNS) using reactor antineutrinos from the Chooz nuclear power plant, with ultra-low-threshold CaWO4 cryogenic targets. To achieve the ambitious particle background goal of the order of 100 dru in the CEvNS region of interest (20-200 eV), a multi‑stage rejection strategy is employed, combining passive...

CEνNS and dark matter experiments aim to detect interactions producing low-energy nuclear recoils using cryogenic detectors with excellent energy resolution (~5 eV) and low thresholds (~20 eV). However, these detectors currently lack a proper calibration method to probe new physics. The CRAB (Calibrated Recoils for Accurate Bolometry) experiment aims to calibrate cryogenic detectors with pure...

Low-energy charged-current scattering of electron neutrinos on argon is the dominant interaction channel for observing neutrinos from supernovae with DUNE. It has been demonstrated that the theoretical uncertainty on the cross section in this unobserved energy region imparts significant bias on supernova spectral parameter reconstruction. COHERENT operated COH-Ar-10, a 24 kg single-phase...

The main challenge for coherent elastic neutrino-nucleus scattering (CEvNS) measurements is the development and optimization of detectors capable of observing very low-energy nuclear recoils. Depending on the target material, either scaling to sufficiently large active masses or achieving ultra-low detection thresholds presents the dominant limitation. The latter is particularly critical for...

The NUCLEUS experiment aims to measure CE$\nu$NS of reactor antineutrinos on tungsten nuclei. To do so, NUCLEUS deploys gram-scale CaWO$_\text{4}$ crystals as cryogenic calorimeters with an ultra-low nuclear recoil energy threshold of O(10) eV. The detectors are instrumented with Transition Edge Sensors (TESs), operated at ~10 mK, to read out the phonon signal directly.

The COHERENT collaboration performed a reanalysis of the data collected at Oak Ridge National Laboratory's Spallation Neutron Source with its high-purity germanium detector array, Ge-mini. Reanalysis of the "Campaign-2" dataset was motivated by the successful analysis of the "Campaign-3" dataset; which extended coherent elastic neutrino–nucleus scattering (CEvNS) measurements in Ge-mini to a...

Coherent elastic neutrino nucleus scattering (CEvNS) was first measured experimentally by the COHERENT experiment in 2017 and is currently being studied by many experiments all around the world.

CONUS+ has recently achieved the first detection of coherent elastic neutrino-nucleus scattering (CEνNS) of reactor antineutrinos on germanium nuclei in the fully coherent regime, and is now entering a precision phase. The dominant uncertainty in the first measurement was the energy scale, contributing 14% to the signal prediction uncertainty, motivating a dedicated sub-keV calibration...

The Ricochet experiment aims to measure Coherent Elastic Neutrino-Nucleus Scattering (CE$\nu$NS) induced by reactor antineutrinos using an array of 18 42-gram cryogenic germanium calorimeters equipped with simultaneous phonon and ionisation readouts for nuclear/electronic recoil discrimination, operated at $\sim$15 mK at the Institut Laue-Langevin (ILL). Cosmic-ray muons can produce secondary...

The Ricochet experiment aims to detect Coherent Elastic Neutrino-Nucleus Scattering (CE$\nu$NS) from antineutrinos produced at the Institut Laue-Langevin where it was deployed at the end of 2023, 8.8 meters away from the reactor core. The current CE$\nu$NS payload is an array of eighteen 42 g germanium cryogenic calorimeters, operated at 17 mK in a cryostat. To mitigate and reject external...

The COHERENT collaboration has measured coherent elastic neutrino-nucleus scattering (CEvNS) on CsI, argon, and most recently germanium. While efforts are underway to obtain precision measurements of CEvNS on NaI and argon with new tonne-scale detectors, the opportunity of measuring CEvNS on other liquid noble targets with the existing CENNS-10 detector is now present.

Mr Anirban Majumdar (Indian Institute of Science Education and Research Bhopal)
In this talk, I will discuss our recent work on the implications of the neutrino fog in dark matter direct detection experiments, motivated by the recent observation of coherent elastic neutrino--nucleus scattering (CE$\nu$NS) from solar $^8$B neutrinos by the XENONnT collaboration. Neutrino fluxes, primarily of astrophysical origin, constitute an irreducible background for dark matter...
