Last year, the CERN Security Operations Centre detected 27 CERN hosts contacting so-called "tracking domains" used for reconnaissance and associated with national state-sponsored actors
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
The ALICE, CMS and LHCb collaborations present new measurements that show how particles containing charm quarks can serve as “messengers” of hadrons and the quark–gluon plasma, carrying information about these forms of matter
