Query: Masses and magnetic moments of hadrons with one and two open heavy
  quarks: heavy baryons and tetraquarks   In this work, we compute masses and magnetic moments of the heavy baryons and
tetraquarks with one and two open heavy flavors in a unified framework of MIT
bag model. Using the parameters of MIT bag model, we confirm that an extra
binding energy, which is supposed to exist between heavy quarks ($c$ and $b$)
and between heavy and strange quarks in literatures, is required to reconcile
light hadrons with heavy hadrons. Numerical calculations are made for all light
mesons, heavy hadrons with one and two open heavy flavors, predicting the
masses of doubly charmed baryons to be $ M(\Xi _{cc})=3.604$ GeV, $ M(\Xi
_{cc}^{\ast })=3.714$ GeV, and that of the strange isosinglet tetraquark
$ud\bar{s}\bar{c}$ with $J^{P}=0^{+}$ to be $ M\left(
ud\bar{s}\bar{c},0^{+}\right) =2.934$ GeV. The state mixing due to
chromomagnetic interaction is shown to be sizable for the strange scalar
tetraquark $nn\bar{s}\bar{c}$.
