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