Query: Taste breaking in staggered fermions from random matrix theory   We discuss the construction of a chiral random matrix model for staggered
fermions. This model includes $O(a^2)$ corrections to the continuum limit of
staggered fermions and is related to the zero momentum limit of the Lee-Sharpe
Lagrangian for staggered fermions. The naive construction based on a specific
expansion in lattice spacing ($a$) of the Dirac matrix produces the term which
gives the dominant contribution to the observed taste splitting in the pion
masses. A more careful analysis can include extra terms which are also
consistent with the symmetries of staggered fermions. Lastly I will mention
possible uses of the model including studies of topology and fractional powers
of the fermion determinant.
