	Hypercharge - Wikipedia, the free encyclopedia
		Do not confuse this hypercharge, related to the strong interaction, with similarly named weak hypercharge, which has an analogous role in the electroweak interaction.
		Hypercharge was a concept developed in the mid-to-late 1900's, to organize groups of particles in the "subatomic zoo" and to develop ad-hoc conservation laws based on their observed transformations.
		Weak hypercharge, however, remains of practical use in various theories of the electroweak interaction.

	SU(3) Theory of Quantized Charge and Hypercharge I (Site not responding. Last check: 2007-11-03)
		With a 3x3 unitary unimodular matrix of eight angles which is compatible with diagonalizing isospin and hypercharge, the representative matrix method is applied to generate a left and a right rotation of differential representation.
		Noticeably, differential operators of iospin, charge, hypercharge, and strangeness are constructed from the H differential operators2.
		Examples of calculating the eigenvalues of the isospin, charge, hypercharge, and strangeness operators operating on on the light and the vector meson wave functions are shown.

		Even the verification of hypercharge is unlikely to seriously affect the principle, according to Peter Saulsan, a principle research scientist for the MIT Department of Physics.
		The principal differences between hypercharge and gravity appear to lie in the forces' effective range and strength, Saulsan said.
		Experiments conducted as far as one kilometer underground by Frank D. Stacey of the University of Queensland in Australia indicate that the force of gravity varies by as much as seven-tenths of one percent at different depths in the earth.

	PHYS146 Notes Spin and Isospin
		The group of particles with similar mass and the same hypercharge is called an isospin multiplet.
		Hypercharge was defined to agree with one of the quantities in group theory, and its name was chosen to reflect its relation to electric charge.
		It is also known that the smallest groups (except for the group of one particle) involving quantities like isospin and hypercharge contain three members (triplets).

	Weak Axis (Site not responding. Last check: 2007-11-03)
		Charge is associated with electro-magnetic forces, and baryon number with the strong nuclear force.
		Hypercharge and isospin are other quantum properties associated with the weak force.
		As a symmetrical particle chart could not be created using strangeness, hypercharge or isospin, I have defined a quantized property that seems to be more fundamentally associated with the weak force.

	Significance of isospin and hypercharge Text - Physics Forums Library
		Isospin and either hypercharge or strangeness are the quantum numbers often used to draw particle diagrams for the hadrons.
		In any of these three cases, it is important to note that the mixing is over corresponding particles in the different families, and that the families differ only in their masses.
		Thus the photon is a mixture of a weak isospin and weak hypercharge interaction.

	Explain Particle Chart
		The subatomic particles are expressions of the fundamental orthogonal, bipolar, quantized aspect of nature, as they can be differentiated from one another on the basis of their dimensions in terms of a small set of quantized properties.
		It seems clear that charge is an independent property associated with electro-magnetic interactions and that baryon number is an independent property associated with strong interactions However, strangeness, hypercharge and isospin appear to be composite properties which can be associated with more than one type of interaction.
		Although isospin, strangeness and hypercharge contain a component sensitive to the weak force, in order to create a symmetrical property chart, I have found it necessary to define a property I will call weakness.

	Was a fifth force felt? - hypercharge or baryon number theory Science News - Find Articles
		The baryon number is related to the number of neutrons and protons, and therefore to the chemical composition of a material--thus explaining the difference in force for different materials.
		The researchers propose a formal similarity between this hypercharge force and electromagnetism.
		Just as electromagnetic forces are carried from object to object by intermediary particles called photons, so this hypercharge force would be carried by "hyperphotons.' A number of experiments could test for the existence of the hypercharge force, including a direct search for the hyperphotons themselves.

		Perhaps, the paper speculates, there is new and very weak force associated with hypercharge which is responsible for the anomalies in both the gravitational and the kaon measurements.
		This test was not a new experiment but a re-analysis of the Eötvös Experiment, the famous experimental comparison of inertial and gravitational mass performed by a Hungarian count in the early decades of this century and published only after his death in 1922.
		The reason is that the hypercharge of a nucleus depends strictly on the number of neutrons and protons in the nucleus, while the mass of a nucleus depends also on the binding energy of the system.

		Of the four, only S(U(3)xU(2)) offers a hypercharge quantization condition which motivates the different hypercharges in a family of quarks and leptons.
		Explicit tensor representations of the quarks and leptons are given and are compared to the standard SU(5) assignments.
		Chapter 1 concludes by imposing the anomaly cancellation conditions with those of hypercharge quantization to uniquely determine the ratios of the hypercharges in a standard quark-lepton family.

		Thus, the physicists contend, if an iron ball and, say, a feather were released simultaneously in a vacuum, the iron's repulsive hypercharge would act more strongly than the feather's to counteract the earth's gravity--and the feather would hit first.
		The team began looking for evidence of hypercharge after perceiving what Fischbach calls "funny results" in two contemporary experiments, one involving gravity tests in a deep mine, the other the behavior of subatomic particles.
		Re-examining the data, the team decided that the aberrations were caused by hypercharge.

	Re: Hi, I've got a question about isospin and quark generations:
		As you may already suspect, most of the textbooks on particle physics are written by professors who were active in the field before quarks were accepted as established theory.
		Before all of the different baryons and mesons were understood to be different combinations of quarks, physicists in the 1960s like Murray Gell-Mann were making sense of the particle "zoo" by organizing particles with the same spin according to their isospin and hypercharge.
		New particles could be predicted and their properties estimated simply by observing the symmetries of each particle group.

		The hypercharge of a subatomic particle is the sum of its baryon number and its strangeness.

		Abstract: The correlation of the fractionally represented hypercharge group with the isospin and colour group in the standard model determines as faithfully represented internal group the quotient group U(1)\ThetaSU(2)\ThetaSU(3) ZZ 2 \Theta ZZ 3.
		The discrete cyclic central abelian-nonabelian internal correlation involved is considered with respect to its consequences for the representations by the standard model fields, the electroweak mixing angle and the symmetry breakdown.

		An analysis of representations of SU(3) in an SU(2) basis is given using SU(2) shift operators.
		It is found that, part from the hypercharge operator, there are two further SU(2) scalar Hermitian operators whose diagonalization leads to new bases for the representation space.
		These are modified to provide a basis which appears more suited to a description of the pseudoscalar meson octet than does the usual basis with diagonal hypercharge.
