Query: Heavy quark symmetry constraints on semileptonic form factors and decay
  widths of doubly heavy baryons   We show how heavy quark symmetry constraints on doubly heavy baryon
semileptonic decay widths can be used to test the validity of different quark
model calculations. The large discrepancies in the results observed between
different quark model approaches can be understood in terms of a severe
violation of heavy quark spin symmetry constraints by some of those models.
