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 […]

Figure The quest to search for new physics inspires searches in CMS for very rare processes, which, if discovered, could open the door to a new understanding of particle physics. One such process is the production […]

Figure In two publications submitted to the Journal of High Energy Physics and Physics Letters B in December, the ALICE collaboration reports new production cross-section measurements of the charmed baryons Λ+c and Ξ0c in proton–proton collisions […]

The APPEC report Multi-messenger astronomy, neutrino physics and dark matter are among several topics in astroparticle physics set to take priority in Europe in the coming years, according to a report by the Astroparticle Physics European Consortium (APPEC). […]

A proton beamline at TRIUMF Researchers at TRIUMF in Canada have reported the first production of ultracold neutrons (UCN), marking an important step towards a future neutron electric dipole moment (nEDM) experiment at the Vancouver laboratory. Precision measurements of the […]

The new ExTrA facility A new national facility at La Silla Observatory in Chile, operated by the European Southern Observatory (ESO), made its first observations at the beginning of the year. ExTrA (Exoplanets in Transits and their Atmospheres) will […]

Figure Measuring the production of the top quark with vector bosons can provide fresh insight into the Standard Model (SM), in particular by testing the top quark and heavy vector boson vertices, which may be modified […]

AAA’s HQ Global healthcare company Novartis has announced plans to acquire Advanced Accelerator Applications (AAA), a spin-off radiopharmaceutical firm established by former CERN physicist Stefano Buono in 2002. With an expected price of $3.9B, said the firm […]

Let there be light At 10.50 a.m. on 22 November 2017, the third-generation light source SESAME in Jordan produced its first X-ray photons, signalling the start of the regional laboratory’s experimental program. Researchers sent a beam of monochromatic light through […]

Experimental The free-electron X-ray laser SwissFEL at the Paul Scherrer Institute (PSI) in Switzerland has hosted its inaugural experiment, marking the facility’s first science result and demonstrating that its many complex components are working as expected. […]

Comparing results The possibility that dark-matter particles may interact via an unknown force, felt only feebly by Standard Model (SM) particles, has motivated an effort to search for so-called dark forces. The force-carrying particle for such hypothesised […]
