Quarks - Term Paper

Quarks

- any group of subatomic particles believed to be among the basic
components if matter
are believed to be the fundamental constituents of matter, and
have no apparent structure. They are the particles that make up protons and
neutrons, which make up the nucleus of atoms. Also, particles that interact by
means of the strong force, the force that holds parts of the nucleus together,
are explained in terms of quarks. Other baryons are explained in terms of
quarks(1985 Quarks).
Quarks have mass and exhibit spin, the type of intrinsic angular
momentum corresponding to rotation around an axis, equal to half the basic
quantum mechanical unit of angular momentum, obeying Pauli's exclusion ...

Up and down quarks make up protons and neutrons, and can be observed
in ordinary matter. Strange quarks can be observed in omega-minus and other
short lived subatomic particles which play on part in ordinary matter(1985
Quarks).
The interpretation of quarks as physical entities poses two problems.
First, sometimes two or three identical quarks have to be in the same quantum
state which, because they have to have half integral spin, violates Pauli's
exclusion principal. Second, quarks appear to not be able to be separated from
the particles they make up. Although the force holding the quarks together is
strong it is improbable that it could withstand bombardment from high energy and
neutrinions in a particle accelorator(1985 Quarks).
Quantum chromodynamics(QCD) ascribes colours red, green, and blue to
quarks and minus-red, minus-green, and minus-blue to antiquarks. Combinations
of quarks must contain equal mixtures of colours so that they cancel each other
out. Colour ...
