Aspects of Symmetry: Selected Erice Lectures
Thus, if the hypercharge of the singlet is y, the hypercharge of the doublet is 1 +y.
Now, if hypercharge rotations are to be a subgroup of SU(3), the hypercharge
itself must be a generator of SU(3). The generators of unimodular matrices are ...

Introduction to Elementary Particle Physics
The quantity corresponding to U(1) is called weak hypercharge or simply
hypercharge, Y W . All the members of the same isospin multiplet have the same
hypercharge. Hypercharge can be defined in two equivalent ways, as twice the
average ...

is a quantity that is not determined in the framework of the isospin symmetry
alone. Equation (6.5) defines the so called hypercharge Y. The idea of
hypercharge goes back to Gell-Mann and Nishijima} who introduced it
independently in 1953.

Recall that the 5L/j3)f quark model is based on two quantum labels, hypercharge
and the third component of isospin, which tag the particles in a given family. All
the baryons of the baryon octet and all the eight mesons of the meson octets, ...
is called the weak hypercharge.2 We see from Eq. (17.25) that Y is related to the
electric charge Q and the weak isocharge if by Y=Q/e-I?. (17.27) The
conservation of the electric charge Q and of the weak isocharge ITM implies
conservation of ...

Quantum Gravity and the Standard Model
It was in 1953 that Gell-Mann and Nishijima found that electric charges of isospin
doublet particles were given by Q = ±1 + 1Y/2, which is the genesis of the
electroweak hypercharge formulaQ = Ι + 1Y, where I is weak isospin charge and
Yis ...

The name hypercharge or strangeness was given to this hypothetical quantity. (
The slight difference in definition of hypercharge and strangeness is not
important to us.) From this view, the strange particles could be produced in pairs
