Study of the ’t Hooft model with the overlap Dirac operator
We present the results of an exploratory numerical study of two dimensional QCD with overlap fermions. We have performed extensive simulations for ${U(N}_{c})$ and ${SU(N}_{c})$ color groups with ${N}_{c}=2,3,4$ and coupling constants chosen to satisfy the 't Hooft condition ${g}^{2}{N}_{c}=\mathrm{const}=4/3.$ We have computed the meson spectrum and decay constants, the …
