In a first for particle physics, the CMS collaboration has observed three J/ψ particles emerging from a single collision between two protons

The ISOLTRAP experiment at CERN’s ISOLDE facility has weighed the neighbouring indium nuclei of tin-100, shedding new light on this special “doubly magic” nucleus

The BASE collaboration has performed the first demonstration of two-trap sympathetic cooling, promising substantial improvements to studies of antiprotons

Discovery of a new exotic hadron containing two charm quarks and an up and a down antiquark

The ATLAS collaboration announces the first observation of WWW production: the simultaneous creation of three massive W bosons in high-energy LHC collisions

The MoEDAL experiment has conducted the first search at a particle collider for magnetic monopoles produced through the Schwinger mechanism

A new technique speeds up deep neural networks for selecting proton–proton collisions at the Large Hadron Collider for further analysis

A new study shows that a class of new unknown particles that could account for the muon’s magnetism, known as leptoquarks, could also affect the Higgs boson’s transformation into muons

New measurements by the ALICE collaboration show that the way charm quarks form hadrons in proton-proton collisions differs significantly from expectations based on electron collider measurements
