   A Relativistic $O(a^2)$ Improved Action for Heavy Quarks

   M.B. Oktay🇺🇸 · A.X. El-Khadra🇺🇸 · A.S. Kronfeld🇺🇸 · P.B. Mackenzie🇺🇸 · J.N. Simone🇺🇸

   We extend the Fermilab formalism for heavy quarks to develop an $O(a^2)$ improved relativistic action. We discuss our construction of the action, including the identification of redundant operators and the calculation of the improvement coefficients.

   Structure functions near the chiral limit

   M. Goeckeler🇩🇪 · R. Horsley🇬🇧 · D. Pleiter🇩🇪 · P.E.L. Rakow🇬🇧 · G. Schierholz🇩🇪

   We compute hadron masses and the lowest moments of unpolarized and polarized nucleon structure functions down to pion masses of 300 MeV, in an effort to make unambiguous predictions at the physical light quark mass.

   Taste-Changing in Staggered Quarks

   Quentin Mason🇺🇸 · Peter Lepage🇺🇸 · Paul Mackenzie🇺🇸 · Howard Trottier🇨🇦 · Joachim Hein🇬🇧 · Christine Davies🇬🇧 · Eduardo Follana🇬🇧

   We present results from a systematic perturbative investigation of taste-changing in improved staggered quarks. We show one-loop taste-changing interactions can be removed perturbatively by an effective four-quark term and calculate the necessary coefficients.
