20N.1.SL.TZ0.30

The Feynman diagram shows some of the changes in a proton–proton collision.

What is the equation for this collision?

A. $p + p \to p + n + π^{+}$

B. $p + p \to p + n + π^{-}$

C. $p + p \to p + \bar{n} + π^{+}$

D. $p + p \to p + \bar{n} + π^{-}$

Examiners report

There were some teacher comments that this was not a complete Feynman diagram however the stem does say that the diagram shows some of the changes and is intended to make the question easier by not complicating with particles that do not change. Students should be made aware that they can expect to see diagrams like this in the future as partial diagrams do tend to make the situation simpler for students to solve.
