Closed k-strings in SU(N) gauge theories: 2+1 dimensions

Abstract:

We calculate the ground state energies of closed k-strings in (2 + 1)-dimensional SU(N) gauge theories, for N = 4, 5, 6, 8 and k = 2, 3, 4. From the dependence of the ground state energy on the string length, we infer that such k-strings are described by an effective string theory that is in the same bosonic universality class (Nambu-Goto) as the fundamental string. When we compare the continuum k-string tensions to the corresponding fundamental string tensions, we find that the ratios are cl...
