The k=2 string tension in four-dimensional SU(N) gauge theories
We calculate the k = 2 string tension in SU(4) and SU(5) gauge theories in 3 + 1 dimensions, and compare it to the k = 1 fundamental string tension. We find, from the continuum extrapolation of our lattice calculations, that σk=2/σf = 1.40±0.08 in the SU(4) gauge theory, and that σk=2/σf = 1.56 ± 0....
