Explainer: what are fundamental particles?

Subatomic particles have shaped and continue to shape our universe but despite perfect predictions by physicists, the theory about unseen particles is still wrong.
Look into my high-energy particle physics and what do you see? CERN

Upgraded LHC pushes physics into the unknown

For less than the cost of a single Typhoon jetfighter, the upgraded LHC will push our understanding of physics to the brink.
Muons, a type of lepton, are studied at the Large Hadron Collider – but what are they? CERN

Explainer: what are leptons?

The giant Large Hadron Collider at CERN’s lab in Europe may be closed until 2015 but experiments will still be run there in the second half of this year on much smaller synchrotrons that examined the decay…
We knew the HIggs boson decayed into bosons; now we’ve seen it crumble into fermions. ATLAS

Higgs boson’s decay confirms physics model works

Last week, the ATLAS experiment at the Large Hadron Collider in Switzerland, showed evidence for the first time that a Higgs boson decays into a pair of tau particles. It is one of the crucial results…
Results pertaining to the Higgs boson are “consistent with its existence”. jef safi

Higgs boson announcement – expert reaction

This expert reaction comes via the Australian Science Media Centre: CERN (the European Organisation for Nuclear Research) has this evening announced that the long-sought Higgs boson probably exists, after…
By smashing together particles at the highest energy readings ever recreated in a laboratory, the Large Hadron Collider, also known as the Big Bang machine, has helped scientists understand the nature of the universe. EPA/Martial Trezzini

Scientists say they have found a Higgs-like particle

Physicists this afternoon announced they have found evidence for a particle considered the biggest missing piece in the standard…
Theoretical physics strives towards a (beautiful) description of everything. Jinx!

Explainer: Standard Model of Particle Physics

The “traditional” beauty of theoretical physics is its equations. If we want to describe something, or the way something behaves, we can write down a relation between some properties we think that thing…
