Why Do Quarks Have Charge
The color charge of quarks and gluons is completely unrelated to the everyday meaning of colorThe term color and the labels red green and blue became popular simply because of the loose analogy to the primary colors. Quarks make up all matter but have never been seen by themselves.
There are six types or flavours of quarks that differ from one another in their mass and charge characteristics.
Why do quarks have charge. Up and down charm and strange and top and bottom. When the color of a combination of quarks is white it is like a neutral atom. The resulting attraction between different quarks causes the formation of composite particles known as hadrons see Strong interaction and color charge below.
For example all quarks have the same spin 12 and three of them up charm and top have charge 23 while the other three down strange and bottom have charge minus 13. Quark color is thought to be similar to charge but with more values. Unlike leptons quarks possess color charge which causes them to engage in the strong interaction.
Quarks can also change from one form to another meaning up quarks can become down quarks according to LiveScience. Even then we still dont know why up and down quarks have those charges. Protons are composed of two up quarks and one down quark so the total charge is 1.
An ion by analogy exerts much stronger forces than a neutral molecule. The creatively-named strong nuclear force is the responsible party as the constituents of protons and neutrons quarks have both electric charges and a new type of charge. How quarks make up the charge on photons and neutrons.
Each one has a. While the protons charge of 1 is due to the sum of the three quarks that make it up two up quarks of 23 and one down quark of -13 the story of its angular momentum is much more. Quarks are confined to the particles they compose.
Why do electrons contain a negative charge and find homework help for other Science questions at eNotes. Electric Charge of Quarks. They have fractional charge.
Up charm and top all have fractional charge of 23 while down strange and bottom all have a charge of -13. For example all quarks have the same spin of ½ with up charm and top having charges of ⅔ and down strange and bottom having charges of -⅓. For example four quarks and an antiquark two quarks-two antiquarks six.
A very interesting quality. The quarks are unusual in that they carry electric charges that are smaller in magnitude than e the size of the charge of the electron 16 10 19 coulomb. As we all know protons have a total charge of 1 e where e is the basic charge of an electron ie.
16 1 0 19 C. Because of the above I am reposting the text below which explains some a priori reasons why quarks come with fractional electric charges in multiples of one third why the sum of charges of fermions in one family nullify and why our universe chose to have quarks of three colours. The color scheme is intentionally devised to explain why baryons have three quarks and mesons have a quark and an antiquark.
And they have flavors and colors though neither term has any relevance to what they actually do. Color charge is a property of quarks and gluons that is related to the particles strong interactions in the theory of quantum chromodynamics QCD. Likewise neutrons are composed of two down quarks and one up quark so the total charge is 0.
Since the neutron has no net electric charge it is not affected by electric forces but the neutron does have a slight distribution of electric charge within it. Since quarks build up almost everything that exists in this universe protons and neutrons are also a combination of quarks. So you can have three quarks three antiquarks a quark-antiquark combination or some combination of the previous three.
This is necessary if quarks are to combine together to give the correct electric charges for the observed particles usually 0 e or e. These six quark flavours can be grouped in three pairs. Quarks associate with one another via the strong force to make up protons and neutrons in much the same way that the latter particles combine in various proportions to make up atomic nuclei.
