A University of Melbourne researcher has placed the strongest constraints yet on certain rare decays of subatomic particles, ...

His work paved the way for the discovery of the Higgs boson, which explained how particles acquire mass, solving one of the ...

Particle accelerators reveal the heart of nuclear matter by smashing together atoms at close to the speed of light. The high-energy collisions produce a shower of subatomic fragments that scientists ...

The standard model (SM) of particle physics is the mathematical description of the fundamental constituents and interactions of matter. Its last missing particle, the Higgs boson, was observed in 2012 ...

The simulation of high-energy particle collisions is an essential task in high-energy nuclear and particle physics and high-energy astroparticle physics. However, although data sets from both fields ...

The Nobel-prize-winning Belgian theoretical physicist François Englert, whose work led to the discovery of the Higgs boson, ...

Secondary particle tracks recorded during a proton collision inside the ATLAS detector, indicating the presence of a single Higgs boson in the event. Since the launch of the Large Hadron Collider, ...

Abstract: Particle, nuclear, and astrophysics experiments are producing massive amounts of data to answer fundamental questions about the basic constituents of our universe. While researchers in these ...

Researchers precisely measured the proton’s size, resolving the proton radius puzzle and strengthening confidence in the Standard Model of particle physics.

How many kinds of elementary particles should I say there are? In experiments at the Large Hadron Collider, physicists smash ...

Sharing disappointing results with a world of researchers working to find what they hope will be the "discovery of the century" isn't an easy task, but that is what Penn State theoretical physicist ...
