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 ...

During the International Conference on High-Energy Physics (ICHEP 2020), the ATLAS collaboration presented the first observation of photon collisions producing pairs of W bosons, elementary particles ...

The standard model (SM) of particle physics has developed as a result of painstaking work, over several decades, by a large number of physicists. It is a quantum field theory, combining quantum ...

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 ...

The current Standard Model of particle physics begins to unravel when probed much beyond the range of current particle accelerators. So no matter what the Large Hadron Collider finds, it is going to ...

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 ...
