The CDF Collaboration at Fermilab has confirmed that a subatomic particle called the Bs meson flips between matter and antimatter about 3 trillion times per second, a measurement so precise it ...

Two independent lines of evidence from the world’s most powerful particle experiments are converging on the same ...

After years of confusion, a new study confirms the proton is tinier than once thought. That enables a test of the standard model of particle physics.

A rare black hole explosion accounts for an “impossible” neutrino detection, say UMass Amherst scientists, possibly hinting ...

Wondering whether whether Dark Matter particles actually are produced inside a jet of standard model particles, led researchers to explore a new detector signature known as semi-visible jets, which ...

Researchers have proposed a whole new way to search for dark matter. A team wants to use CERN’s Large Hadron Collider to look for what are called semi-visible jets”—columns of decaying particles that ...

In 1930, a young physicist named Carl D. Anderson was tasked by his mentor with measuring the energies of cosmic rays—particles arriving at high speed from outer space. Anderson built an improved ...
