LEP’s electroweak leap

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.

Muon g−2 collaboration prepares for first results

Fermilab's E989 experiment aims to improve experimental errors by a factor of four.

Four-muon Higgs candidate in Run-2 ATLAS data

Higgs hunters still hungry in Paris

Some Higgs measurements are on the verge of being systematics dominated.

The excavation of new shafts for the HL-LHC

Report reveals full reach of LHC programme

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.

Probing gauge-boson polarisation

WZ production, with its clean experimental signature, offers a sensitive way to search for anomalies.

Exploring the spin of top-quark pairs

The Standard Model makes precise predictions for the frequency at which the spin of the top quark is aligned with the spin of the top antiquark.

ATLAS observes scattering of vector bosons

The cross-section of longitudinal weak-boson scattering would diverge, resulting in meaningless values, were it not for the exact cancellation due to Higgs-boson contributions.

CMS detects first production of top quark and photon

The predicted cross section for tγj, including the branching fraction, is 81 fb, which corresponds to a few hundred events in the whole dataset.

A decade of advances in jet substructure

Recent focus on measuring Standard Model properties using jet substructure has motivated ATLAS to measure the energy and mass response of large-radius jets with the highest possible precision.
