Though other explanations can’t be ruled out, CMS finds the toponium hypothesis to be sufficient to explain the observed ...

With a new measurement imminent, the Courier explores the experimental results and theoretical calculations used to predict ‘muon g-2’ – one of particle physics’ most precisely known quantities and ...

Quantum Drama, by Jim Baggott and John L Heilbron, Oxford University Press One hundred years of insights Jim Baggott and John Heilbron don’t neglect later quantum pioneers like John Bell (pictured).
