摘要：The comparison between unquenched SU(3) lattice QCD with chemical potential and random
matrix theory can provide information on the pion decay constant F. We calculated eigenvalue
distributions of the Dirac operator on a 834 lattice using Nf = 2 Kogut-Susskind fermions. We
performed ts between the spectral density computed from random matrix theory and lattice data
at coupling = 5:30 for xed quark mass ma = 0:05 and iso-vector chemical potential a = 0:0,
0:004773, 0:1 and 0:2, nding good agreement. In particular our data indicate that F decreases
as the iso-vector chemical potential increases. For a more precise t of the rescaled parameter
2F2
V we also compare to the rst eigenvalue distribution from random matrix theory.
