Query: Extended Nambu--Jona-Lasinio model with eight quark interactions   We review the effect on vacuum properties and magnetic catalysis, of adding
the most general 0-spin 8-quark (8q) interactions to the combined SU(3) flavor
Nambu--Jona-Lasinio (NJL) and 6-quark (6q) 't Hooft interaction Lagrangian.
