Question

Using the up, down and strange quarks only, construct, if possible, a baryon (a) with$\mathit{q}\mathbf{=}\mathbf{+}\mathbf{1}$ and strangeness $\mathit{S}\mathbf{=}\mathbf{-}\mathbf{2}$and (b) with$\mathit{q}\mathbf{=}\mathbf{+}\mathbf{2}$ and strangeness, $\mathit{S}\mathbf{=}\mathbf{0}$.

Short answer

(a) There is no possible baryon.

(b) The baryon is .$uuu$

Step-by-step solution

(a) A baryon with q=+1and strangeness,S=−2 .

There is no possible baryon by the use of up , down and strange quarks with$q=+1$ and strangeness$S=-2$ .

Hence, there is no possible baryon.

(b) A baryon withq=+2  and strangeness, S=0.

The possible baryon of three up quarks is the only which is with $q=+2$and strangeness, $S=0$.

Hence, the possible baryon is .$uuu$
