Problems with the Quenched Approximation in the Chiral Limit
Stephen Sharpe
In the quenched approximation, loops of the light singlet meson (the ) give rise to a type of chiral logarithm absent in full QCD. These logarithms are singular in the chiral l…

Perturbative Corrections for Staggered Fermion Bilinears
Apoorva Patel, Stephen Sharpe
We calculate the perturbative corrections to fermion bilinears that are used in numerical simulations when extracting weak matrix elements using staggered fermions. This extends pr…
