The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

Two Canadian physicists are relishing the news that a pair of subatomic particles they predicted more than five years ago has turned up at the Large Hadron Collider (LHC), the world's premier particle ...

Hints of a new fundamental interaction are starting to look less like statistical ghosts and more like a pattern that refuses ...

Institute for Quantum Computing director Raymond Laflamme (centre) stands with NMR laboratory manager Michael Ditty in front of a nuclear magnetic resonance spectrometer at the institute's liquid ...

Observing light in motion is now possible thanks to an impressive breakthrough by researchers at the University of Toronto. They have developed a technology capable of capturing and simulating the ...

Smashing atomic nuclei together at mind-bending speeds recreates the fiery conditions of the early universe and scientists are finally getting a better handle on what happens next. A sweeping new ...

Data from the Large Hadron Collider (LHC) outside Geneva appears to have proved the existence of particles made of five quarks, solving a 50-year-old puzzle about the building blocks of matter, ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...
