Integrated luminosity On 28 April, 13 days ahead of schedule, operators at CERN’s Large Hadron Collider (LHC) successfully injected 1200 bunches of protons into the machine and brought them into collision – formally marking the beginning of […]

The large centre-of-mass energy and luminosity of the LHC have made possible the first measurements of electroweak-boson production in ultrarelativistic heavy-ion collisions. The production cross sections for such processes in proton–proton (pp) collisions are known with high precision, and indeed have

NA62’s candidate event The NA62 collaboration at CERN has found a candidate event for the ultra-rare decay K+ → π+ ν ν, demonstrating the experiment’s potential to test heavily-suppressed corners of the Standard Model (SM). The SM prediction for the K+ → π+ ν ν branching […]

Figure The TOTEM collaboration at CERN has uncovered possible evidence for a subatomic three-gluon compound called an odderon, first predicted in 1973. The result derives from precise measurements of the probability of proton–proton collisions at high […]

Connection A project carried out at the Technische Universität (TU) Darmstadt in Germany, funded by the European Commission, aims to build a magnetic trap that allows antiprotons to be transported from one location to another. Launched […]

Selected events Measurements of top-quark production at high rapidity in LHC proton–proton collisions provide a unique probe of the Standard Model of particle physics (SM). In this kinematic region, top-pair production is characterised by sizeable rates of […]
