Quarks are elementary particles that are the building blocks of all visible matter in the universe. Explore them in more detail here.

where the quarks are indicated below each baryon. This is a fusion of two singly heavy baryons into a doubly heavy baryon and a nucleon. The masses of all of the particles in reaction (1) are ...

Quarks are the main components of protons. We have concluded through experimental probing of the proton with high energy electrons that inside the proton there are three massive objects, and based ...

By separately scattering right- and left-handed electrons off quarks in a deuterium target, researchers have improved, by about a factor of five, on a classic result of mirror-symmetry breaking ...

This process, called fragmentation, gives physicists clues about how quarks behave when they’re released from the tight grip of the strong nuclear force. Now here’s where the symmetry jumps in.

The discovery of two entangled quarks at the large Hadron Collider is the highest-energy observation of entanglement ever made. When you purchase through links on our site, we may earn an ...

Do top quarks, nature's heaviest elementary particle, obey Einstein's rules at all times of day and night? Scientists at the Large Hadron Collider have the answer.
