| ABSTRACT: |
I discuss a new way to determine two low-energy constants of QCD by means of lattice gauge theory simulations that include imaginary isospin chemical potential. Results derived from the chiral Lagrangian agree exactly with results derived in a Random 2-Matrix Theory, which I will describe in some detail.
