Query: The Flavor Structure of the Excited Baryon Spectra from Lattice QCD   Excited state spectra are calculated using lattice QCD for baryons that can
be formed from $u$, $d$ and $s$ quarks, namely the $N$, $\Delta$, $\Lambda$,
$\Sigma$, $\Xi$ and $\Omega$ families of baryons. Baryonic operators are
constructed from continuum operators that transform as irreducible
representations of SU(3)$_F$ symmetry for flavor, SU(4) symmetry for Dirac
spins of quarks and O(3) symmetry for orbital angular momenta. Covariant
derivatives are used to realize orbital angular momenta. Using the operators,
we calculate matrices of correlation functions in order to extract excited
states. The resulting lattice spectra have bands of baryonic states with
well-defined total spins up to $J=7/2$. Each state can be assigned a dominant
flavor symmetry and the counting of states of each flavor and spin reflects
$SU(6) \times O(3)$ symmetry for the lowest negative-parity and positive-parity
bands. States with strong hybrid content are identified through the dominance
of chromo-magnetic operators.
