Chapter 44: Q25P (page 1364)

The quark makeups of the proton and neutron are $u u d$ and, $u d d$ respectively. What are the quark makeups of (a) the antiproton and (b) the antineutron?

Short Answer

Expert verified

(a) The antiproton is written as. $\overset{炉}{u} \overset{炉}{u} \overset{炉}{d}$

(b) The antineutron is written as. $\overset{炉}{u} \overset{炉}{d} \overset{炉}{d}$

Step by step solution

(a) Quark makeups of the antiproton.

It is given that the quark makeups of the proton is. $u u d$

The antiproton is composition of two up antiquarks and one down antiquark.

Hence, the antiproton is written as. $\overset{炉}{u} \overset{炉}{u} \overset{炉}{d}$

Step 2: (b) Quark makeups of the antineutron.

It is given that the quark makeups of the neutron is. $u d d$

The antiproton is composition of one up antiquarks and two down antiquark.

Hence, the antineutron is written as. $\overset{炉}{u} \overset{炉}{d} \overset{炉}{d}$
