Query: Hadronization of heavy diquark and light quark within NJL-Model   We present a path-integral hadronization for doubly heavy baryons. The two
heavy quarks in the baryon are approximated as a scalar or axial-vector diquark
described by a heavy diquark effective theory. The gluon dynamics are
represented by a NJL-Model interaction for the heavy diquarks and light quarks,
which leads to an effective action of the baryon fields after the quark and
diquark fields are integrated out. This effective action for doubly heavy
baryon includes the electromagnetic and electroweak interactions, as well as
the interaction with light mesons. We also verify the Ward-Takahashi identity
at the baryon level, obtain the Isgur-Wise function for weak transitions, and
calculate the strong coupling constant of the doubly heavy baryon and pion.
Numerical studies are also performed.
