Abstract<\/h3>\n\n\nThe Coherent Neutrino-Nucleus Interaction Experiment (CONNIE) uses low-noise fully depleted charge-coupled devices (CCDs) with the goal of measuring low-energy recoils from coherent elastic scattering (CE<\/span><\/span>\u03bd<\/span><\/span>NS<\/span><\/span><\/span><\/span><\/span><\/span>) of reactor antineutrinos with silicon nuclei and testing nonstandard neutrino interactions (NSI). We report here the first results of the detector array deployed in 2016, considering an active mass 47.6\u00a0g (eight CCDs), which is operating at a distance of 30\u00a0m from the core of the Angra 2 nuclear reactor, with a thermal power of 3.8\u00a0GW. A search for neutrino events is performed by comparing data collected with the reactor on (2.1\u00a0kg-day) and reactor off (1.6\u00a0kg-day). The results show no excess in the reactor-on data, reaching the world record sensitivity down to recoil energies of about 1\u00a0keV (0.1\u00a0keV electron equivalent). A 95%\u00a0confidence level limit for new physics is established at an event rate of 40 times the one expected from the standard model at this energy scale. The results presented here provide a new window to low-energy neutrino physics, allowing one to explore for the first time the energies accessible through the low threshold of CCDs. They will lead to new constraints on NSI from the\u00a0CE<\/span><\/span>\u03bd<\/span><\/span>NS<\/span><\/span><\/span><\/span><\/span><\/span>\u00a0of antineutrinos from nuclear reactors.\nFotograf\u00eda: Imagen de un paquete que incluye el CCD, que est\u00e1 pegado a un marco de silicio; los marcos de cobre superior e inferior; y el cable flexible stage-1.
