The magnet detectives
During a routine test, two HL-LHC magnets unexpectedly flatlined. Was it just a coincidence, or did they have a common foe?

Whatever happened to the theory of everything?
A theory of everything was all the rage in the 1980s. So where did it go?
LHC experiments see four top quarks
The ATLAS and CMS experiments have observed a process 4,000 times rarer than the production of Higgs bosons.
Wait, didn’t the LHC already “restart?”
Today marks the start of LHC Run 3. So what was #restartingLHC in April all about?
Particle Fever: Where are they now?
The 2013 documentary Particle Fever follows physicists from the start-up of the LHC through the discovery of the Higgs boson. Where are those physicists now?
What’s up with the W boson mass?
The CDF experiment at Fermilab measured the mass of the W boson and came up with an answer that no one expected.
Can a theory ever die?
Neglected theories will wilt and wither but can bloom again with enough attention.
Double trouble Higgs
Scientists worried Higgs pairs would be too rare for LHC experiments to find. But by using machine learning, they now are getting tantalizingly close.
What’s new for LHC Run 3?
CERN’s accelerators and the LHC’s detectors have undergone major upgrades that will allow scientists to collect more data in the upcoming run than they did in the previous two runs combined.
