Closed flux tubes and their string description in D=2+1 SU(N) gauge theories
We calculate the energy spectrum of a confining flux tube that is closed around a spatial torus, as a function of its length ℓ. We do so for various SU(N) gauge theories in 3+1 dimensions, and for various values of spin, parity and longitudinal momentum. We are able to present usefully accurate resu...
