Our fifth story in the LHC Physics at Ten series looks at how the LHC has recreated and greatly advanced our knowledge of the state of matter that is believed to have existed shortly after the Big Bang

The BASE collaboration is developing a transportable antiproton trap to make higher-precision measurements of the properties of antimatter

The LHCb collaboration has observed time-dependent matter–antimatter asymmetry in the decays of strange beauty particles into charged kaons

The result opens the path to study in a new and unique way the extreme state of matter that is thought to have existed shortly after the Big Bang

The NA63 collaboration has made a high-precision study of the phenomenon of radiation reaction, using particle beams and crystals

The finding is significant for both fundamental and medical research, as the element is a promising candidate for cancer treatment by targeted alpha therapy

Our fourth story in the LHC Physics at Ten series discusses the LHC’s hunt for the hypothetical particle that may make up dark matter

Researchers have conducted the first search at a hadron collider for elementary particles with electric charges smaller than a tenth of the electron charge

Chris Parkes takes the baton from Giovanni Passaleva

The NA64 collaboration has conducted its first search for axions and axion-like particles, targeting an unexplored area

Cosmic-ray data collected by the AMS detector on the International Space Station again challenge conventional theory of cosmic-ray origin and propagation

A combination of theoretical calculations and information from astronomical observations indicates that massive neutron stars can contain cores filled with free quarks
