The antineutron has a quark structure _________.
A) uud
B) udd
C) u$\overline{u}$d
D) $ \overline{u}~ \overline{d}~ \overline{d} $
E) ${ u } \bar { d } d$

Quizplus · Accepted Answer

The antineutron is the antiparticle of the neutron, which has a quark structure of udd. Therefore, the antineutron has the corresponding antiquark structure of $\overline{u}\overline{d}\overline{d}$.

The Antineutron Has a Quark Structure _________ u‾\overline{u}u D D) u‾ d‾ d‾ \overline{u}~ \overline{d}~ \overline{d} u d d

The Antineutron Has a Quark Structure _________ $\overline{u}$ D
D) $\overline{u}~ \overline{d}~ \overline{d}$
