Weak hypercharge is twice the difference between the Electrical Charge and the Weak Isospin . It is the generator of the center of the electroweak gauge group. In a relation that parallels the Gell-Mann/Nishima Law (see Hypercharge ) we have : where ''Q'' is the electrical charge (in Elementary Charge units), is the third component of the Weak Isospin , and is the weak hypercharge. From here we can define the weak hypercharge in terms of particle electrical charge and weak isospin. Given that weak isospin is 1/2 for all left-handed fermions (and 0 for all right-handed fermions), all weak isospin doublets will have an average charge : with
