CMS has made a novel measurement of the top-quark mass by reconstructing boosted top quarks as single jets.
A new ATLAS analysis cuts a swathe into the parameter space for one well-motivated alternative electroweak symmetry breaking sector.
The ATLAS and CMS collaborations have obtained new insights into the charge-parity structure of top-Higgs interactions.
The LHC’s physics programme has transformed our understanding of elementary particles, writes Michelangelo Mangano.
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.
