Chapter 44: Q26P (page 1364)

From tables 44-3 and 44-5, determine the identity of the baryon formed from quarks (a), $d d u$ (b), $u u s$ and (c) $s s d$ .Check your answers against the baryon octet shown in Fig 44-3a.

Short Answer

Expert verified

(a) The Baryon formed from the quark $u u s$ is proton. $(p)$

(b) The Baryon formed from the quark $u u s$ is proton. $(p)$

Step by step solution

(a) Determine the identity of the baryon formed from quarks ddu.

The quark bundle

The total charge is calculated as,

$\begin{matrix} Q = (- \frac{1}{3}) + (- \frac{1}{3}) + (\frac{2}{3}) \\ = 0 \end{matrix}$

Total strangeness; $S = 0$

Here charge and strangeness coincides with the neutron.

Hence, the Baryon formed from the quark $d d u$ as neutron . $(n)$

(b) Determine the identity of the baryon formed from quarks uus.

The quark bundle

The total charge is calculated as,

$\begin{matrix} Q = (\frac{2}{3}) + (\frac{2}{3}) + (- \frac{1}{3}) \\ = 1 \end{matrix}$

Total strangeness;

$\begin{matrix} S = 0 + 0 - 1 \\ = - 1 \end{matrix}$

Here charge and strangeness coincides with the $\sum^{+}$ particle.

Hence, the Baryon formed from the quark $u u s$ is proton . $(p)$

(c) The identity of the baryon formed from quarks ssd.

The quark bundle $s s d$

The total charge is calculated as,

$\begin{matrix} Q = (- \frac{1}{3}) + (- \frac{1}{3}) + (- \frac{1}{3}) \\ = - 1 \end{matrix}$

Total strangeness;

$\begin{matrix} S = - 1 + (- 1) + 0 \\ = - 2 \end{matrix}$

Here charge and strangeness coincides with the $\sum^{+}$ particle.

Hence, the Baryon formed from the quark $s s d$ is. $?^{-}$
