In the very early, very hot moments of the universe, the electromagnetic and weak nuclear forces were actually the same force—the electroweak interaction. Scientists can now study this interaction ...

Display of a candidate event for the production of two W+ bosons via vector-boson scattering, followed by their decay into two muons and two muon neutrinos. The muons are represented by the red lines ...

Observational first: physicists have used the ATLAS experiment at CERN to observe the production of top-quark and photon pairs. (Courtesy: CERN) For the first time, particle physicists have observed ...

Elusive fundamental particles called neutrinos are predicted to interact unexpectedly with photons under extreme conditions. Research at Hokkaido University has revealed that elusive particles called ...

Today, the universe as we know it is governed by four fundamental forces: the strong nuclear force, the weak nuclear force, electromagnetism, and gravity. However, these four forces aren’t exactly as ...
