The Standard Model of Particle Physics is the best theory scientists have to explain how the universe works on subatomic ...

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 ...

It is once again stocky particle spring. You might recall that, one year ago, researchers at Fermilab announced the discovery of a fat wobbly muon. Now, they have another offering for us: a boson with ...

Most of the matter in the universe may be made out of particles that possess an unusual, donut-shaped electromagnetic field called an anapole. This proposal, which endows dark matter particles with a ...

A new theory suggests the universe’s greatest secrets are hiding in a “zeptouniverse” that’s ready to be explored—without waiting until 2070 for a new collider.

"When my student showed me the data I thought she must be wrong," Boston College professor and lead researcher Kenneth Burch told Live Science. "It's not every day you find a new particle sitting on ...

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.

When matter and antimatter meet, they annihilate, releasing energy in the form of radiation. Such encounters are governed by Einstein’s famous equation, E=mc 2 — energy equals mass times the square of ...
