摘要：
An excess of high-energy events has been found in previous ANTARES searches for a diffuse flux of cosmic neutrinos, consistent in spectral slope and normalisation with the cosmic neutrino signal detected by the IceCube Neutrino Observatory. The analysis of ANTARES data can provide valuable information in the study of this high-energy neutrino signal, especially in the case of soft-spectra solutions. To improve previous ANTARES results, a new event selection has been developed for cascade-like events, relying on a boosted decision tree multivariate-analysis technique. This yields a 5-fold increase in event statistics, while also reducing the surviving foregrounds and the related systematic uncertainties. This contribution will report on the status of the analysis and the prospects emerging from the use of this new event sample in the search for a diffuse flux of cosmic neutrinos.
