Read article 'First low-mass dielectron results ahead of LHC Run 3'
In contrast to strongly interacting hadronic probes, dielectrons provide an unperturbed view into the quark–gluon plasma.
Read article '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.
Read article 'Fixed-target physics in collider mode at LHCb'
The LHCb fixed-target system, known as SMOG, injects a small amount of noble gas inside the LHC beam pipe.
Read article 'Observation of Higgs-boson decay to bottom quarks'
Processes that include the Higgs boson’s favoured decay mode to b quarks (with about 58% probability) have until now remained elusive.
Read article 'Solving the mystery of a historic stellar blast'
Some 180 years ago, a relatively normal star called Eta Carinae suddenly brightened to become the second brightest star in the sky, before almost disappearing at the end of the 19th century.

He received many honours, including election to a fellow of the Royal Society and the Hughes Medal for his work at CERN on g-2.
Read article 'IceCube neutrino points to origin of cosmic rays'
On 22 September 2017, IceCube registered a 300 TeV neutrino of astrophysical origin, triggering worldwide follow-up observations.
Read article 'CMS looks into the dark'
If dark-QCD mediators were produced in pairs in the CMS detector, their signature would be striking.
Read article 'LHCb tests consistency of unitarity triangle'
The unitarity triangle exists in the complex plane and its area is a measure of the amount of CP violation in the Standard Model.
