Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter ...

Composite image of the Tycho Supernova remnant. Shock waves from such explosive events are believed to be the main drivers behind cosmic rays. Scientists have come a step closer to understanding how ...

This sample of niobium has been treated in a process that is typical for preparing particle accelerator components. Tests have revealed how adding oxygen to such components makes them more efficient.

The key test passed by sPHENIX to prove it is ready to measure the properties of quark-gluon plasma is called a "standard candle" in particle physics. This isn't to be confused with Type 1a supernovas ...

DURHAM, N.C. -- One of the tiniest building blocks of the universe has a weigh-in problem, and Ashutosh Kotwal is determined to get to the bottom of it. For nearly 30 years, the Duke physicist has led ...

GENEVA — After a quarter-century of searching, scientists have nailed down how one particularly rare subatomic particle decays into something else — a discovery that adds certainty to our thinking ...

The KM3NeT underwater telescope detects a record-breaking neutrino of hundreds of PeV, marking the beginning of a new era.

Whether this CP-flipped particle behaves the same way as the original electron is a key question: If it doesn’t, physicists say that CP symmetry is “violated.” Any examples of CP symmetry violation in ...
