The weak nuclear force doesn't play by the normal rules — and, in fact, it breaks one of the biggest rules of all.

On February 13, 2023, a single subatomic particle zipped across the Mediterranean Sea off the coast of Sicily, triggering ...

An artist's concept of multiple types of subatomic particles. Forget about turtles; for all practical purposes, it’s really particles all the way down. Consider the seemingly simple matter of their ...

ABSTRACT: The Daya Bay Collaboration has discovered that approximately 6.0% of active neutrinos were missing from the nuclear reaction container. This finding has led to a reinterpretation of the ...

Dartmouth researchers propose that dark matter began as light-speed particles that suddenly gained mass through spin interactions and cooling. Their theory, inspired by superconductivity, outlines a ...

Scientists have discovered semi-Dirac fermions, quasiparticles that behave as massless in one direction and massive in another, inside a crystal of ZrSiS. This discovery, achieved using advanced ...

Scientists first suggested a type of particle called a semi-Dirac fermion 16 years ago. They thought these particles could change their mass depending on their moving direction. In one direction, they ...

Illustration of a quasiparticle. Credit: EPFL. A team of researchers has now observed something physicists had only theorized: a quasiparticle that behaves like it has mass when moving one way and ...

An illustration of the calculated structure of ZrSiS near the crossing points of its structure, showing a semi-Dirac point as a black sphere on the left. Data points as purple dots support the ...
