The second edition of the Summer School is held from 10 to 15 September 2023 in Macugnaga (VB). It is devoted to students at upper 4th and 5th grade, who in 5 days explore with their teachers the issues related to the natural radioactivity present in the mountain environment that hosts us.

Flavia Groppi, professor of Health Physics of the Department and INFN Section of Milan and Mariagabriella Pugliese, University of Naples Federico II - INFN Section Naples are awarded the SIF 2023 prize for Scientific Communication.

The ATLAS experiment at CERN sets record precision on the Higgs boson’s mass: the brand new result states that the mass value is 125.11±0.11 GeV. With a remarkable accuracy of 0.09%, this currently stands as the most precise determination of the Higgs-boson mass. The measurement saw a fundamental contribution from the Milano analysis team.

A new monograph on the theory of the physical properties of disordered solids (or amorphous solids), by Alessio Zaccone, has been published in the Lecture Notes in Physics book series.

The journal Nature has published a study by an international team of researchers announcing the discovery of JD1, an extremely distant and faint galaxy, using the James Webb Space Telescope and exploiting the strong gravitational lensing effect.

PBS Space Time has produced a video on the discovery of evidence for an intrinsic charm quark component of the proton. The discovery, published in 2022 on Nature, was made by the NNPDF collaboration, led by Prof. Stefano Forte of the Physics Department.
