Paper of the month:  Search for an anomalous excess of inclusive charged-currentνe interactions in the MicroBooNE experiment using Wire-Cell reconstruct

November 23, 2021 by RebecaBV

Abstract: There are a number of anomalies in the neutrino sector, among which we can find the LSND and MiniBooNE appearance anomalies at short baselines. These could point to an oscillation driven by a sterile neutrino with a mass around 1 eV, which are present in many neutrino mass models. Nonetheless, MiniBooNE’s results could also originate from a SM background source, given the experimental difficulties in differentiating between photons and electrons. After several years of running, MicroBooNE has finally provided with the first data addressing MiniBooNE’s anomalous excess of events, which we discuss in the following.

Figure 1: Event number in the MiniBooNE detector (black dots) as a function of the visible energy. The different shaded regions correspond to different contributions to the expected event rate.

Figure 2: Event number in the MicroBooNE detector (black dots) as a function of the reconstructed neutrino energy (upper panel), together with the eLEE prediction (red-dashed lines). The lower panel corresponds to the ratio between the data and the prediction without eLEE.
