https://phys.org/ en-us Latest news from INFN In the recent past, space missions dedicated to the study of astrophysical signals in the high-energy spectrum revealed a series of enigmatic excesses not predicted by the theoretical models. In order to find an explanation for these anomalies, many solutions have been proposed. The most exciting hypothesis invokes the contribution of the elusive dark matter, the mysterious form of matter four times more abundant than baryonic matter, and of which scientists have so far detected only gravitational effects. https://phys.org/news/2021-03-dark-source-excess-gamma-rays.html Astronomy Mon, 29 Mar 2021 10:32:17 EDT news536232734 The authors of a study published in Physical Review D have shown that coherent neutrino scattering with nuclei provides a novel way to measure the neutrino charge radii. This interaction was theoretically predicted more than 40 years ago, but the difficulty of measuring the very small nuclear recoil inhibited its experimental observation until 2017 by the COHERENT experiment. https://phys.org/news/2019-01-neutrinos-mysterious.html General Physics Mon, 07 Jan 2019 09:28:26 EST news466075676 (Phys.org) —Borexino is a liquid scintillator detector mainly built for solar neutrino searches. Due to its high level of radiopurity, a worldwide record, Borexino can also detect rare events such as electron-antineutrinos from the interior of the Earth, namely geo-neutrinos. https://phys.org/news/2013-03-results-geo-neutrinos-borexino.html General Physics Thu, 14 Mar 2013 08:47:22 EDT news282469628 (Phys.org) -- The OPERA collaboration has announced yesterday at the Neutrino 2012 conference in Japan, the observation of their second neutrino tau interaction, after the first observation made in 2010. https://phys.org/news/2012-06-opera-tau-neutrino.html General Physics Thu, 07 Jun 2012 06:25:34 EDT news258268996
