Quark - Wikipedia Elementary fermions are grouped into three generations, each comprising two leptons and two quarks The first generation includes up and down quarks, the second strange and charm quarks, and the third bottom and top quarks
Quarks: What are they? | Space Quarks are elementary particles that are the building blocks of all visible matter in the universe Explore them in more detail here
Quark | Definition, Flavors, Colors | Britannica quark, any member of a group of elementary subatomic particles that interact by means of the strong force and are believed to be among the fundamental constituents of matter
What Are Quarks? Building Blocks of Everything Quarks are tiny, mysterious particles that, together with gluons and leptons, compose all matter in the universe They are the essential constituents of protons, neutrons, and many other particles, and they obey mind-bending rules that challenge our everyday intuition
DOE Explains. . . Quarks and Gluons - Department of Energy There are six different kinds of quarks with a wide range of masses They are named up, down, charm, strange, top, and bottom Quarks are the only elementary particles to experience all the known forces of nature and to have a fractional electric charge
Deciphering the heavyweights of the tetraquark world | CERN Illustration of a tetraquark composed of two charm quarks and two charm antiquarks (Image: CERN) To date, the Large Hadron Collider (LHC) at CERN has discovered 80 particles The most famous is the Higgs boson, a crucial ingredient in the fundamental laws of the Universe The rest are particles called hadrons made up of quarks, which allow physicists to investigate the intriguing properties
Quarks - HyperPhysics Quarks are observed to occur only in combinations of two quarks (mesons), three quarks (baryons) There was a recent claim of observation of particles with five quarks (pentaquark), but further experimentation has not borne it out
