The Circular Electron–Positron Collider (CEPC), a 100-km electron–positron “Higgs factory” proposed in China, has reached the technical-design stage but will not be included for approval or construction in the country’s 15th Five-Year Plan (2026–2030).

Symmetry between up and down quarks is more broken than expected
Surprising results from the NA61/SHINE collaboration #AtCERN show that this so-called isospin asymmetry could point to gaps in physicists’ understanding of how quarks and gluons combine.
