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 ...

Researchers have uncovered a counterintuitive phenomenon in collision dynamics: high-speed particles bounce back from wet walls much more strongly than expected. Integrating experimental observations ...

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 ...

Elastic collisions in one dimension are a clear example of physics in action, where both momentum and kinetic energy remain unchanged. With the right formulas, you can predict exactly how objects will ...

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 ...

After the collision, the team hit the scattered molecules with a tagging laser tuned to specific energy levels. If a molecule was in a matching quantum state, it absorbed the laser's energy, creating ...
