Ausdehnung der Elektronen und Quarks feststellen, das heisst, sie sind kleiner als 10** Meter und damit mindestens 10 Milliarden mal kleiner als ein Atom.

The smallest particle in the classic physics is te atom. In the modern physics is the quark quark is the composition of an eletron.
An atom is the smallest part of an element. The atom consists of nucleus with protons and neutrons and electrons surrounding the nucleus.
Both the neutron and proton are hadrons composed of quarks. The electron is a quark. The least massive particle in an atom is a quark. Proton, neutron and electron At a lower level up quark, down quark, and electron.
Yes, a quark is smaller than an atom. Much smaller. Quarks are fundamental particles, and three quarks make up protons and neutrons, which in turn make up atoms.
The particle is called the "Quark". Yes, a proton is built from two up-quarks and one down-quark. There are 3 parts to an atom: 1. Protons 2.
Neutrons 3. Electrons The electrons are the smallest of the 3 and therefor weigh the least. A proton is composed of 2 up quarks and 1 down quark while a neutron is composed of 1 up quark and 2 down quarks.
The Up Quark weighs more than the Down quark. Therefore, the proton would weigh more. See Photon exhange to see how an Up quark turns in a Down quark through photon exchange.
A quark is a fundamental subatomic particle, or class of subatomic particles. It is smaller than an atom. The nucleus of an atom contains protons and neutrons, which are comprised of up and down quarks.
The proton contains two up quarks and one down quark, while the neutron contains one up quark and two down quarks.
The binding forces carried by the gluons tend to be weak when quarks are close together. This condition is called asymptotic freedom. When one begins to draw the quarks apart, however, as when attempting to knock them out of a proton, the effect of the force grows stronger.
This is because, as explained by QCD, gluons have the ability to create other gluons as they move between quarks.
The larger the number of gluons exchanged among quarks, the stronger the effective binding forces become. Supplying additional energy to extract the quark only results in the conversion of that energy into new quarks and antiquarks with which the first quark combines.
In two independent groups of scientists at the Fermi National Accelerator Laboratory reported that they had found the top quark.
Their results give the top quark a mass of The next heaviest quark, the bottom, has a mass of about 4. Quark Article Media Additional Info.

Green Quarks and Nuclei. McMahon Quantum Field Theory Demystified. Roth The decay process for the lambda particle must violate that rule, since there is no lighter particle which contains a strange quark - so the strange quark must be transformed to another quark in the process.
That can only occur by the weak interaction , and that leads to a much longer lifetime. The decay processes show that strangeness is not conserved: The quark transformations necessary to accomplish these decay processes can be visualized with the help of Feynman diagrams.
The omega-minus , a baryon composed of three strange quarks, is a classic example of the need for the property called " color " in describing particles.
So with three strange quarks, the property which distinguishes them must be capable of at least three distinct values.
Conservation of strangeness is not in fact an independent conservation law, but can be viewed as a combination of the conservation of charge, isospin , and baryon number.
It is often expressed in terms of hypercharge Y, defined by:. Isospin and either hypercharge or strangeness are the quantum numbers often used to draw particle diagrams for the hadrons.
With a mass of MeV, over three times that of the proton, this particle was the first example of another quark , called the charm quark. Richter and Ting shared the Nobel Prize for their discovery.
The lightest meson which contains a charm quark is the D meson. It provides interesting examples of decay since the charm quark must be transformed into a strange quark by the weak interaction in order for it to decay.
Convincing evidence for the observation of the top quark was reported by Fermilab 's Tevatron facility in April The evidence was found in the collision products of 0.
The evidence involved analysis of trillions of 1. The Collider Detector Facility group had found 56 top candidates over a predicted background of 23 and the D0 group found 17 events over a predicted background of 3.
The value for the top quark mass from the combined data of the two groups after the completion of the run was This is over times the mass of a proton and about twice the mass of the next heaviest fundamental particle, the Z0 vector boson at about 93 GeV.Glashow; J.
