Quantum mechanics, developed a century ago, has long challenged conventional views of nature. At its core lies the principle of wave-particle duality, which shows that quantum objects can behave like ...

When fundamental particles are heavier or lighter than expected, physicists' understanding of the universe can tip into the unknown. A particle that is just beyond its predicted mass can unravel ...

A new imaging technique using a particle accelerator is giving researchers an unprecedented level of detail of our organs, producing scans 100 billion times brighter than a CT scanner. Those 3D models ...

A weird force that skirts traditional physics norms has helped erase a smudge on the foundations of particle physics. It’s a phenomenon called the “neutrino force,” by which neutrinos could ...

A pair of rare particles produced in high-energy proton collisions may be the clearest evidence yet that mass can emerge from empty space. The finding could shed light on one of the biggest puzzles in ...

"This is the first time we have observed, for a large interval in momentum and for multiple species, this flow pattern in a subset of proton collisions in which an unusually large number of particles ...
