Color triplet excitations in two dimensional QCD

Abstract

We present a novel calculation of color triplet excitations in two dimensional QCD with SU(2) colors. It is found that the lowest energy of the color triplet excitations is proportional to the box length $L$, and can be written as ${\cal M}_C={L\over{2π}}{g^2\overπ} $. Therefore, the color triplet excited states go to infinity when the system size becomes infinity. The properties of the color triplet states such as the wave functions are studied for the finite box length.
