As yet we can only guess what the Higgs boson might look like. DESY Zeuthen

Explainer: the Higgs boson particle

Theoretical physics is full of mysteries and unknowns. In the case of some particles, we can predict their existence even if we can’t find them. Such is the status of the Higgs boson. And yet detecting…
Is the “Z-prime” lurking within a “jungle” of particles at the LHC? Argonne National Laboratory

Explainer: the Z' (hypothetical) particle

There’s nothing like an unexpected result to get physicists excited. So in 2008, when some strange behaviour was detected from a rarely-produced particle known as the “top quark”, there was much interest…
Could neutrinos be responsible for the shape of the universe? The Super-Kamiokande Neutrino Detector, Japan

Explainer: the elusive neutrino

Of all the known particles in our universe, neutrinos are perhaps the most elusive; their origins are mysterious, their purpose unknown and they are notoriously difficult to detect. You’ll already know…
