High-energy neutrinos are extremely rare particles that have so far proved very difficult to detect. Fluxes of these rare particles were first detected by the IceCube Collaboration back in 2013.
Magnets, those everyday objects we stick to our fridges, all share a unique characteristic: they always have both a north and a south pole. Even if you tried breaking a magnet in half, the poles would not separate—you would ...

Where did all the antimatter go? After the Big Bang, matter and antimatter should have been created in equal amounts. Why we live in a universe of matter, with very little antimatter, remains a mystery. The excess of matter ...

A new computational analysis by theorists at the U.S. Department of Energy's Brookhaven National Laboratory and Wayne State University supports the idea that photons (a.k.a. particles of light) colliding with heavy ions can ...

Visible matter—everything from pollen to stars and galaxies—accounts for roughly 15% of the total mass of the universe. The remaining 85% is made of something entirely different from things we can touch and see: dark ...

New particles sensitive to the strong interaction might be produced in abundance in the proton-proton collisions generated by the Large Hadron Collider (LHC) – provided that they aren't too heavy. These particles could ...

As the heaviest known elementary particle, the top quark has a special place in the physics studied at the Large Hadron Collider (LHC) at CERN. Top quark-antiquark pairs are copiously produced in collisions recorded by the ...
