Quantum particles behave in strange ways and are often difficult to study experimentally. Using mathematical methods drawn from game theory, physicists have shown how bosons, which like to enter the ...

The strange behaviour of a fundamental particle called a muon may hint at the existence of exotic particles and forces beyond the standard model of physics. We have had signs of this anomaly before, ...
