Projected Sensitivities

CEvNS - The large number of opportunities to study non-standard neutrinos interaction in the low energy range –below the inverse beta decay process– along with the observation of the CEvNs interaction, have witnessed a growing interest during the last years. In this contest, we propose a short baseline reactor neutrino experiment to cover three orders of magnitude of unexplored energy range for neutrino interaction using 10 kg of Skipper-CCD detectors with an energy threshold of approximately 1 eV. We discuss constraints to the SM and also benchmark beyond SM. In particular, we claim that our prospective for the exposure time required for observing the CEvNs at a 90% of confidence level at one of the most powerful nuclear reactors available in Argentina is only 1.5 days
Measuring the weak mixing angle - We analyze in detail the physics potential of an experiment like the one recently proposed by the vIOLETA collaboration: a kilogram-scale Skipper CCD detector deployed 12 meters away from a commercial nuclear reactor core. This experiment would be able to detect coherent elastic neutrino nucleus scattering from reactor neutrinos, capitalizing on the exceptionally low ionization energy threshold of Skipper CCDs. To estimate the physics reach, we elect the measurement of the weak mixing angle as a case study. We choose a realistic benchmark experimental setup and perform variations on this benchmark to understand the role of quenching factor and its systematic uncertainties,background rate and spectral shape, total exposure, and reactor antineutrino flux uncertainty. We take full advantage of the reactor flux measurement of the Daya Bay collaboration to perform a data driven analysis which is, up to a certain extent, independent of the theoretical uncertainties on the reactor antineutrino flux. We show that, under reasonable assumptions, this experimental setup may provide a competitive measurement of the weak mixing angle at few MeV scale with neutrino-nucleus scattering.
Neutrino Magnetic Moment - This spectra present all the contributions where NMM is measured. At very low energy, the number of events expected by CEvNS are pretty similar to the one expected by background, it is around 1 kdru. Thus, this channel twice the competing signal events summing up electron and nucleus contributions. By contrast, weak interaction produced a negligible number of events at such low energies. As a result we get a Bayesian upper limit as good as 10^-11 Bohr magneton after running vIOLETA for 3 years.
