Sm. Nishigaki et al., SMALLEST DIRAC EIGENVALUE DISTRIBUTION FROM RANDOM-MATRIX THEORY - ART. NO. 087704, Physical review. D. Particles and fields, 5808(8), 1998, pp. 7704
We derive the hole probability and the distribution of the smallest ei
genvalue of chiral Hermitian random matrices corresponding to Dirac op
erators coupled to massive quarks in QCD. They are expressed in terms
of the QCD partition function in the mesoscopic regime. Their universa
lity is explicitly related to that of the microscopic massive Bessel k
ernel. [S0556-2821(98)03118-X].
