Constraints on models with light mediators from the latest CONNIE results

Not scheduled


Brenda Aurea Cervantes Vergara


The CONNIE experiment, located at a distance of 30 m from the core of the Angra 2 reactor in Brazil, has collected a 3.7 kg-day exposure using a CCD detector array, with an energy threshold of $\sim$1 keV, for the study of coherent elastic neutrino-nucleus scattering (CE$\nu$NS). We report the first results of the experiment showing no excess in the reactor-on data. A 95% confidence level limit was established and was used to constrain two simplified extensions of the Standard Model with light mediators. The constraints for a light vector with mass $M_{Z^{\prime}}<$ 10 MeV and a light scalar with mass $M_{\phi}<$ 30 MeV are the current best limits among the experiments searching for CE$\nu$NS.
