Proton–lead run tops record year of LHC operations
On 26 October, the LHC completed its 2016 proton–proton operations at a collision energy of 13 TeV, during which it exceeded the design value of the luminosity and broke many other records (CERN C...

ATLAS makes precision measurement of W mass
A precise measurement of the mass of the W boson, which was discovered at CERN in 1983, is vital because it is closely related to the masses of the top quark and the Higgs boson.

Run 2 promises a harvest of beauty for LHCb
The first b-physics analysis using data from LHC Run 2, which began in 2015 with proton–proton collisions at an energy of 13 TeV, shows great promise for the physics programme of LHCb. During 201...

ALICE zeroes in on cold-matter effects
Measuring the production cross-section of charm hadrons in proton–proton collisions provides an important test of perturbative quantum chromodynamics (QCD). In proton–nucleus collisions, “cold-m...

Protons probe quark–gluon plasma at CMS
Proton–nucleus collisions provide a crucial tool to investigate the quark–gluon plasma (QGP), a state of nuclear matter with a high energy density spread over a relatively large volume. Although p...
