View ArticleMeasurements of the light-by-light scattering and the Breit--Wheeler...
Measurements of the light-by-light scattering (LbL, $\gamma\gamma\to\gamma\gamma$) and the Breit--Wheeler (B--W, $\gamma\gamma\to\mathrm{e}^+\mathrm{e}^-$) processes are reported in ultraperipheral...

View ArticleMeasurement of azimuthal correlations among jets and determination of the...
A measurement is presented of the ratio observable $R_{\Delta\phi}(p_\mathrm{T})$ that provides a measure of the azimuthal correlations among jets with large transverse momentum $p_\mathrm{T}$. The...
View ArticleMeasurements of Higgs boson properties in decays to two $\tau$ leptons and...
Three analyses exploiting the $H\rightarrow\tau\tau$ process using 139 fb$^{-1}$ of proton--proton collision data collected at a center-of-mass energy of 13 TeV by the ATLAS detector at the LHC are...
View ArticleThe CCube reconstruction algorithm for the SoLid experiment
The SoLid experiment is a very-short-baseline experiment aimed at searching for nuclear reactor-produced active to sterile antineutrino oscillations. The detection principle is based on the pairing of...
View ArticleDesign and early operation of a new-generation internal beam dump for CERN’s...
The Super Proton Synchrotron (SPS) is the last stage in the injector chain for CERN's Large Hadron Collider, and it also provides proton and ion beams for several fixed-target experiments. The SPS has...
View ArticleNuclear charge radii of germanium isotopes around $N$ = 40
Collinear laser spectroscopy measurements were performed on $^{68-74}$Ge isotopes ($Z = 32$) at ISOLDE-CERN, by probing the $4s^2 4p^2 \, ^3\!P_1 \rightarrow 4s^2 4p 5s \, ^3\!P_1^o$ atomic transition...
View ArticleFast-switching magnet serving a spallation-driven ultracold neutron source
A fast-switching, high-repetition-rate magnet and power supply have been developed for and operated at TRIUMF, to deliver a proton beam to the new ultracold neutron (UCN) facility. The facility...

Search for charged-lepton-flavour violating $\mu\tau qt$ interactions in top-quark production and decay in pp collisions at $\sqrt{s}=13$ TeV with the ATLAS detector at the LHC
View ArticleMeasurement of multijet azimuthal correlations and determination of the...
A measurement is presented of a ratio observable that provides a measure of the azimuthal correlations among jets with large transverse momentum $ p_{\mathrm{T}} $. This observable is measured in...
View ArticleTechnologies for Social Innovation (TeSI) 2024 at IdeaSquare
Technologies for Social Innovation (TeSI) is a project course where, in this first round, student teams and their instructors collaborate with researchers at CERN to discover novel solutions for the...

As part of the event: "The virtuous circle of knowledge and innovation", presentation of Alessandra Lombardi about Particle Accelerators Probing the infinitely small
View ArticleNP07: ND280 Upgrade status report
The upgrade of the T2K Near Detector, ND280, has been approved by the SPSC in April 2019 and it is one of the Neutrino Platform projects (NP07). In this document, prepared for the SPSC Annual review,...
