The ATLAS experiment at CERN has published its first measurements of proton–oxygen collisions, simulating cosmic-ray impacts on Earth's atmosphere. The high-precision results, achieved at a few ...
Tens of kilometers above Earth's surface, high-energy particles from outer space constantly strike the atmosphere, creating ...
One of the biggest open questions in particle physics today is how the Higgs boson interacts with itself. This "self-coupling" could help explain the evolution of the early universe and the mechanism ...
