We introduce and study a class of discrete particle ensembles that naturally arise in
connection with classical random matrix ensembles, log-gases and Jack polynomials.
Under technical assumptions on a general analytic potential we prove that the
global fluctuations of these ensembles are asymptotically Gaussian with a
universal covariance that remarkably differs from its counterpart in random
matrix theory. Our main tools are certain novel algebraic identities that we
have discovered. They play a role of discrete multilevel analogues of loop
equations.
