28. Since only the strange quark (s) has non-zero strangeness, in order to obtain S = 1 we need to combine s with some non-strange antiquark (which would have the negative of the quantum numbers listed in Table 45-5). The difficulty is that the charge of the strange quark is 1 / 3, which means that (to obtain a total charge of + 1) the antiquark would have to have a charge of

Unformatted text preview: + 4 3 . Clearly, there are no such antiquarks in our list. Thus, a meson with S = − 1 and q = +1 cannot be formed with the quarks/antiquarks of Table 45-5. Similarly, one can show that, since no quark has q = − 4 3 , there cannot be a meson with S = +1 and q = − 1....
