Query: Strange and charm baryon masses with two flavors of dynamical twisted
  mass fermions   The masses of the low-lying strange and charm baryons are evaluated using two
degenerate flavors of twisted mass sea quarks for pion masses in the range of
about 260 MeV to 450 MeV. The strange and charm valence quark masses are tuned
to reproduce the mass of the kaon and D-meson at the physical point. The
tree-level Symanzik improved gauge action is employed. We use three values of
the lattice spacing, corresponding to $\beta=3.9$, $\beta=4.05$ and $\beta=4.2$
with $r_0/a=5.22(2)$, $r_0/a=6.61(3)$ and $r_0/a=8.31(5)$ respectively.
%spacings $a=0.0855(5)$ and $a=0.0667(3)$ determined from the pion decay
constant. We examine the dependence of the strange and charm baryons on the
lattice spacing and strange and charm quark masses. The pion mass dependence is
studied and physical results are obtained using heavy baryon chiral
perturbation theory to extrapolate to the physical point.
