Chapter 32, Problem 37P

To determine

(a) To determine:

Find the quark combinations for

${\Xi }^0$ baryon

Answer to Problem 37P

Solution:

uss

Explanation of Solution

The charge of ${\Xi }^0$ baryon is 0. Thus, the quark combination for ${\Xi }^0$ baryon should also have charge 0. The quark up(u)and strange(s)have charge $\frac{2}{3}$ and $-\frac{1}{3}$

The quark combination for ${\Xi }^0$ baryon is uss.

To determine

(b) To determine:

Find the quark combinations for

${\Xi }^{-}$ baryon

Answer to Problem 37P

Solution:

dss

Explanation of Solution

The charge of ${\Xi }^{-}$ baryon is -1. Thus, the quark combination for ${\Xi }^{-}$ baryon should also have charge -1. The quark down(d)and strange(s)have charge $-\frac{1}{3}$ and $-\frac{1}{3}$

The quark combination for ${\Xi }^0$ baryon is dss.
