a particle that is acted upon by the strong force. Quarks exist in six varieties (up, down, charm, strange, top, bottom) and three "colors" (red, green, blue).
This is one of the elementary particles which are the building blocks of hadrons.
One of the subatomic particles from which many modern theoreticians believe such elementary particles as protons and neutrons are composed. The various kinds of quarks have positive or negative charges of 1/3 or 2/3.
fundamental constituent of protons and neutrons, in much the same manner that the latter are constituents of nuclei — — CLOSE
A subatomic particle found in the nucleus of the atom.
Particles of which all hadrons are supposed to be composed.
any of several elementary particles that are postulated to come in pairs of similar mass with one member having a +2/3 charge and the other having a -2/3 charge
a fundamental particle, which possesses both electric charge and 'strong' charge
an elemental particle studied by high-energy physicists seeking to understand the ultimate nature of matter
a small particle in an atom that flys around electrons
general name given to any of six hypothetical particles believed to make up protons and neutrons
A (charged) elementary particle that feels the strong force. Protons and neutrons are each composed of three quarks.
Quarks are fundamental particles from which hadrons are formed. There are six types of quarks; up, down, charm, strange, top and bottom. Each has a spin of ½ and a charge of -1/3 or +2/3. Quarks are bound together through the exchange of gluons. Each quark has a corresponding antiquark as its antimatter particle.
A sub-atomic particle, thought to be the simplest of all particles. The quark theory was devised by the physicist Gell-Mann to explain the complex interactions of sub-atomic particles. They were named after a line from James Joyces's novel "Finnegan's Wake", "three quarks for Muster Mark".
An Elementary Particle which makes up the Neutron and the Proton, as well as many more exotic particles. These particles are Fermions, and have charges of either 2/3 as much as an electron's charge, or -1/3. They come in "flavors" of up, down, strange, charmed, bottom, and top, as well is in "colors" of red green and blue. The "flavor" and "color" are just fanciful names given to describe intrinsic properties of these particles—similar to charge, mass, or spin.
The basic building block of matter, and the foundation for modern theories of matter and the universe. Quarks combine with gluons to make the protons and neutrons that make up every atom in the universe. There are six varieties of quark: up and down, which make up most everyday matter, and the more exotic top, bottom, strange and charm quarks.
A fractionally charged, basic building block of protons, neutrons, and other elementary particles.
An elementary, strongly interacting constituent of matter. Quarks come in six flavors: up, down, charm, strange, top and bottom. The up, charm and top quarks have electric charges of +(2/3)e, while the down, strange and bottom quarks have charges of -(1/3)e. The proton which has a charge of +e is constructed of two up quarks and one down quark: (uud), while the neutron is (udd).
A hypothetical basic subatomic nuclear particle believed to be the basic component of protons, neutrons, etc.
(q): A fundamental fermion that has strong interactions. Quarks have electric charge of either +2/3 (up, charm, top) or -1/3 (down, strange, bottom) in units where the proton charge is 1.
one of the two basic building blocks of matter (Scientists have discovered six different kinds of quarks: Top, Bottom, Up, Down, Strange and Charm.)
an elementary particle that is affected by the strong force. All hadrons contain quarks.
A type of elementary particle.
A strongly-interacting fermion that is a building block of hadronic matter. Quarks come in six flavors: up, down, charm, strange, top, bottom.
A fundamental particle, building block of protons and neutrons, as well as all other hadrons and mesons. There are six different quarks, tow in each of he three families of matter.
elementary particle, that constitutes protons and neutrons.
Any of a group of subatomic particles believed to be among the fundamental constituents of matter. In much the same way that protons and neutrons make up atomic nuclei, these particles themselves are thought to consist of quarks.
Hypothetical truly fundamental particle in mesons and baryons; there are supposed to be six flavours of quarks (and their antiquarks), which come in pairs; each has an electric charge of +2/3 or -1/3.
Quarks are subatomic particles that may be the fundamental constituents of baryons (like protons and neutrons) and mesons (like pions and kaons). Quarks have mass, charge (plus or minus 1/3 or 2/3), and spin. There are six types of quarks: up, down, strange, charm, top, and bottom. Baryons are made of 3 quarks each (protons and neutrons are made of up and down quarks); mesons are made of 2 quarks (a quark and an anti-quark). Murray Gell-Mann proposed the existence of quarks in 1964.
An elementary particle which is believed to be the fundamental structural unit from which all other particles are made. There are six quarks: up, down, strange, charm, top and bottom. A proton is made up of one down quark and two up quarks.
In particle physics, quarks are one of the two basic constituents of matter (the other are the leptons). Quarks are the only fundamental particles that interact through all four of the fundamental forces. The word was borrowed by Murray Gell-Mann from the book Finnegans Wake by James Joyce, where seabirds give "three quarks", akin to three cheers (probably onomatopoetically imitating a seabird call, like "quack" for ducks).
