This is the most precise measurement so far of a parameter with implications for the stability of the vacuum.
ATLAS has released a slew of top-quark results, including a production cross section and mass and charge-asymmetry measurements.
Prior to the BESIII result published in May, the Particle Data Group listing for ⍺- had remained unchanged since 1978.
Higgs-boson measurements are entering the precision regime.
Achieving 8% precision on the Higgs cross section is a significant step towards studying the electroweak symmetry breaking mechanism.
In the autumn of 1989 the Large Electron Positron collider (LEP) delivered the first of several results that still dominate the landscape of particle physics today.
Fermilab's E989 experiment aims to improve experimental errors by a factor of four.
Some Higgs measurements are on the verge of being systematics dominated.
The High-Luminosity LHC, scheduled to operate from 2026, will increase the instantaneous luminosity of the LHC by at least a factor of five beyond its initial design luminosity.
WZ production, with its clean experimental signature, offers a sensitive way to search for anomalies.
