Symmetry between up and down quarks is more broken than expected
Surprising results from the NA61/SHINE collaboration at CERN show that this so-called isospin asymmetry could point to gaps in physicists’ understanding of how quarks and gluons combine
Optical fibre link to make CERN more on time than ever
A new optical fibre link between CERN and Paris will provide the Laboratory with an accurate frequency reference, enhancing precision and supporting experiments like ALPHA in their search for matter–antimatter differences
