Abstract: (DESY)
We establish a close relation between the spatial string tension of the (3+1)-dimensional SU(3)SU(3) gauge theory at finite temperature (σs\sigma_s) and the string tension of the 3-dimensional SU(3)SU(3) gauge theory (σ3\sigma_3) which is similar to what has been found previously for SU(2)SU(2). We obtain σ3=(0.554±0.004)g3 2\sqrt{\sigma_3} = (0.554 \pm 0.004) g_3~2 and σs=(0.586±0.045)g 2(T)T\sqrt{\sigma_s} = (0.586 \pm 0.045)g~2(T) T, respectively. For temperatures larger than twice the critical temperature results are consistent with a temperature dependent coupling running according to the two-loop β\beta-function with ΛT=0.118(36)Tc\Lambda_T = 0.118(36)T_c.
