QCD_2 in the axial gauge revisited
Yu. S. Kalashnikova, A. V. Nefediev
The 't Hooft model for the two-dimensional QCD in the limit of infinite number of colours is studied in the axial gauge. The mass-gap and the bound-state equations are derived usin…
Classical antiparticles, quantum supersymmetry anomaly and constituent models
Yu. S. Kalashnikova, A. V. Nefediev
The two ways of constrained systems quantization are considered from the point of view of their self-consistency at the quantum level. With a transparent example of a particle in t…
QCD_2 in the modified Fock-Schwinger gauge
Yu. S. Kalashnikova, A. V. Nefediev
The system of light quark and heavy antiquark source is studied in 1+1 QCD in the large N_C limit. The situation is demonstrated to be the two dimensional analogue of the problem i…
Constituent string model for hybrid mesonic excitations
Yu. S. Kalashnikova, Yu. B. Yufryakov
The model for hybrid excitations of the QCD string with quarks is presented starting from the perturbation theory in the nonperturbative background. The propagation of a system con…
