Particle Physics

Quark-gluon plasma, a bizarre state of matter that mimics the early cosmos, is the hottest thing ever made on Earth

Theorists have found that a “warm” version of cosmic inflation is consistent with known physics, linking it to the hunt for dark matter

The answer to this supposedly simple particle physics question isn’t so simple

Federal officials seized 3,000 copies of Scientific American in 1950 in a “red scare” era of attacks on science. The move backfired and offers lessons for today

A relatively small detector caught neutrinos from a nuclear reactor using a technique known as coherent scattering

Researchers hoped CMB-S4, a $900-million cosmology experiment, would answer one of the greatest questions in physics. Instead it’s become another cautionary tale of pursuing big science amid shrinking budgets

The LHCb experiment has observed a new difference between matter and antimatter in particles called baryons

Inspired by superconductivity, a strange new theory that seeks to explain dark matter might explain dark energy, too

The most anticipated particle physics result of recent years is here—but the real news came one week before: the “muon g–2 anomaly” might have never existed

A freak particle physics process could wipe out all galaxies and life—but it’s wildly unlikely

Researchers have shown that abstract mathematical functions from the frontiers of theoretical physics have a real-world use in modeling gravitational waves

Scientists at Europe’s famous particle collider briefly created gold ions from lead in a modern twist on the alchemical goal
