Abstract:
Employing the functional renormalization group approach at next-to-leading order of the derivative expansion, we refine our earlier findings for the location of the Yang-Lee edge singularity in classic OoN thorn universality classes. For the universality classes of interest to QCD, in three dimensions, we found x 1/4 1.612o9 thorn , 1.597o3 thorn for N 1/4 2, 4 correspondingly. We also established jzcj 1/4 2.04o8 thorn , 1.69o3 thorn for N 1/4 2, 4 albeit with greater systematic error.
