  If any violation of Lorentz symmetry exists in the hadron sector, its
ultimate origins must lie at the quark level. We continue the analysis of how
the theories at these two levels are connected, using chiral perturbation
theory. Considering a two-flavor quark theory, with dimension-4 operators that
break Lorentz symmetry, we derive a low-energy theory of pions and nucleons
that is invariant under local chiral transformations and includes the coupling
to external fields. The pure meson and baryon sectors, as well as the couplings
between them and the couplings to external electromagnetic and weak gauge
fields, contain forms of Lorentz violation which depend on linear combinations
of quark-level coefficients. In particular, at leading order the
electromagnetic couplings depend on the very same combinations as appear in the
free particle propagators. This means that observations of electromagnetic
processes involving hadrons--such as vacuum Cerenkov radiation, which may be
allowed in Lorentz-violating theories--can only reliably constrain certain
particular combinations of quark coefficients.
