Problem 39

Draw a possible Feynman diagram using quarks (as in Fig. 32–17c) for the reaction $\pi^-$ + p $\rightarrow \pi^0$ + n.

(c) Quark representation of the same interaction neutron + proton -> neutron + proton. The blue coiled lines between quarks represent gluon exchanges holding the hadrons together.

Figure 32-17 (c) Quark representation of the same interaction

n + p \rightarrow n + p

. The blue coiled lines between quarks represent gluon exchanges holding the hadrons together. (The exchanged meson may be regarded as

\bar{\textrm{u}}\textrm{d}

emitted by the n and absorbed by the p, or as

\textrm{u}\bar{\textrm{d}}

emitted by p and absorbed by n, because a u (or d) quark going to the left in the diagram is equivalent to a

\bar{\textrm{u}}

(or

\bar{\textrm{d}}

) going to the right.)
