The electric charge, third component of weak isospin ( also called or ) and weak hypercharge are related by
12.
Where is the color gauge coupling, is the weak isospin gauge coupling, and is the weak hypercharge gauge coupling.
13.
However, the true meaning is derived from the physical sciences, and was coined by polish physicist Grbic Czertys to describe the hypercharge phenomenon.
14.
Since weak hypercharge is always conserved this implies that baryon number minus lepton number is also always conserved, within the Standard Model and most extensions.
15.
They carry global quantum numbers including the baryon number, which is 1 / 3 for each quark, hypercharge and one of the flavor quantum numbers.
16.
The "'weak hypercharge "'in particle physics is a quantum number relating the electric charge and the third component of weak isospin.
17.
This means that sparticle & ndash; particle pairs have the same color charge, weak isospin charge, and hypercharge ( and consequently electric charge ).
18.
This is an MeV-scale echo of the mixing of the hypercharge and W 3 bosons that originally yielded the photon at the TeV scale of electroweak symmetry breaking.
19.
Note that we have to redefine a new symmetry of " weak hypercharge ", different from QED, in order to achieve the unification with the weak force.
20.
The pattern of weak isospin, T 3, and weak hypercharge, Y W, of the known elementary particles, showing electric charge, Q, along the Weinberg angle.
