Quarks and antiquarks are the teeny, tiny building blocks with which all matter is built, binding together to form protons and neutrons in a process explained by quantum chromodynamics (QCD).

Quantum chromodynamics is an area of study that explores the strong interactions between quarks mediated by gluons. Quarks are elementary particles with an electric charge, which are building blocks ...

During the evolution of the Universe there were particle-physics-related transitions. Although there are strong indications of an inflationary period, we know little about how it affected possible ...

Nuclear physics research is focused on understanding the matter composed of quarks and gluons, which makes up 99% of the mass of the universe. Most of this matter is found at the core of atoms, the ...

Artist’s depiction of a proton’s interior. In quantum chromodynamics, the constituent quarks come in three “colors,” along with up and down “flavors.” Also shown are virtual quark-antiquark pairs and ...

Quantum chromodynamics (QCD) is the theory that describes the interactions governed by the strong nuclear force. Where electromagnetism is mediated by the photon and the weak force by the W and Z ...

The life and death of a star can largely be described based on its mass. Below the Chandrasekhar limit—about 1.4 times the mass of the sun—a star will end its life as a white dwarf. Stars that weigh ...

Quarks and antiquarks are the teeny, tiny building blocks with which all matter is built, binding together to form protons and neutrons in a process explained by quantum chromodynamics (QCD).

Quantum Chromodynamics (QCD) is universally accepted today as the theory of strong interactions. Nevertheless, many conceptual questions, like those concerning the properties of the quark gluon plasma ...
