Particle accelerators reveal the heart of nuclear matter by smashing together atoms at close to the speed of light. The ...

At CERN’s Large Hadron Collider on the edge of Geneva, scientists have reported a surprising twist in the behavior of matter. Collisions inside the 27‑kilometer ring have produced what researchers ...

Collision physics is a research area within atomic, molecular, and optical physics that investigates the fundamental processes occurring when particles such as atoms, ions, electrons, or molecules ...

Relativistic heavy-ion collisions produce a high density of partons with strong final-state interactions and lead to the formation of the quark-gluon plasma (QGP). Experimental evidence at the ...

An international team of physicists has studied how particles are produced in high-energy electron–proton collisions through the lens of entanglement entropy Entanglement entropy has emerged as a new ...

Inside high-energy proton collisions, quarks and gluons briefly form a dense, boiling state before cooling into ordinary particles. Researchers expected this transition to change how disordered the ...

Explore collision physics by learning how to determine elasticity in train car crashes! This video breaks down the concepts of elastic and inelastic collisions, momentum conservation, and energy ...
