  Chiral symmerty is presumed to be a crucial component in the strong
interaction and QCD, but its role in spectroscopy, especially for baryons, has
not been fully explored. Compounding this, chiral fermions are uncommon in
lattice calculations due to their expensive nature. We calculate $\eta\pi$,
$K\pi$ and $N\pi$ states with $q\bar{q}$ and $qqq$ interpolation fields at
$a=0.114\,\mathrm{fm}$ on a $48^3\times 96$ mixed-action lattice at the
physical pion mass, with domain-wall sea quarks and overlap valence quarks. We
study the spectral weights of these states as a function of the valence pion
mass, which ranges from $m_{\pi}=115-665\,\mathrm{MeV}$, to be compared with
the results from non-chiral clover valence quarks on the same domain-wall
lattice in order to examine their non-chiral effects, which are expected to
decrease with the lattice spacing.
