A New Computation Of The Correlation Length Near The Deconfining Transition In Su(3)

We compute the correlation length of an SU(3) gauge system in the neighbourhood of the deconfining phase transition by measuring loop-loop correlation functions. We find values that are linearly divergent with the lattice size at the critical point and fully compatible with our former estimates obtained by using a cold source method. Together with a precise determination of the location of the critical point these results make stronger the evidence for a large ξ at β close to β c .
