Query: Improving QCD with fermions: the 2 dimensional case of QCD with Sea
  Quarks   We study QCD in 2 dimensions using the improved lattice fermionic Hamiltonian
proposed by Luo, Chen, Xu and Jiang. The vector mass and the chiral condensate
are computed for various $SU(N_C)$ gauge groups. We do observe considerable
improvement in comparison with the Wilson quark case.
