New calculations suggest the muon anomaly may be resolved, reinforcing confidence in the Standard Model of particle physics.

Lattice QCD unlocks precision The team overcame the challenge of calculating strong-force effects by using lattice quantum chromodynamics, simulating space-time on a fine grid with supercomputers.

Muon is the heavier cousin (around 200 times) of the electron. It is produced when cosmic rays interact with Earth’s ...

Very soon after the Big Bang, the universe enjoyed a brief phase where quarks and gluons roamed freely, not yet joined up into hadrons such as protons, neutrons and mesons. This state, called a ...

Polarized proton containing spinning quarks and gluons (represented by right-handed and left-handed spirals). The negative Δg solutions (blue) are disfavored relative to the positive Δg solutions (red ...

Recent research has shown that the trace anomaly can be measured using the production of charmonium. This is a type of subatomic particle produced at the Thomas Jefferson National Laboratory and the ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

An international team has produced the most precise calculation yet of the muon's magnetic moment, resolving a decades-long discrepancy with experimental results. The new hybrid method, combining ...
