  Using a Poincar\'e-covariant quark+diquark Faddeev equation, we provide
structural information on the four lightest
$(I,J^P)=(\tfrac{1}{2},\tfrac{3}{2}^\mp)$ baryon multiplets. These systems may
contain five distinct types of diquarks; but in order to obtain reliable
results, it is sufficient to retain only isoscalar-scalar and
isovector-axialvector correlations, with the latter being especially important.
Viewed with low resolution, the Faddeev equation description of these states
bears some resemblance to the associated quark model pictures; namely, they
form a set of states related via orbital angular momentum excitation: the
negative parity states are primarily $\mathsf P$-wave in character, whereas the
positive parity states are $\mathsf D$ wave. However, a closer look reveals far
greater structural complexity than is typical of quark model descriptions, with
$\mathsf P$, $\mathsf D$, $\mathsf S$, $\mathsf F$ waves and interferences
between them all playing a large role in forming observables. Large momentum
transfer resonance electroexcitation measurements can be used to test these
predictions and may thereby provide insights into the nature of emergent hadron
mass.
