23 Apr 1992 | | Journal: | Int.J.Mod.Phys. A7 (1992) 8001-8020 | | Subject: | hep-th | | Abstract: | We show that baryons of three dimensional Quantum Chromodynamics can be understood as solitons of its effective lagrangian. In the parity preserving phase we study, these baryons are fermions for odd $N_c$ and bosons for even $N_c$, never anyons. We quantize the collective variables of the solitons and there by calculate the flavor quantum numbers, magnetic moments and mass splittings of the baryon. The flavor quantum numbers are in agreement with naive quark model for the low lying states. The magnetic moments and mass splittings are smaller in the soliton model by a factor of $log {F_piover N_c m_pi}$. We also show that there is a dibaryon solution that is an analogue of the deuteron. These solitons can describe defects in a quantum anti--ferromagnet. | | Source: | arXiv, hep-th/9204076 | | Services: | Forum | Review | PDF | Favorites | |
