Mass renormalisation for improved staggered quarks
J. Hein🇬🇧 · Q. Mason🇺🇸 · G.P. Lepage🇺🇸 · H. Trottier🇨🇦
Abstract
Improved staggered quark actions are designed to suppress flavour changing strong interactions. We discuss the perturbation theory for this type of actions and show the improvements to reduce the quark mass renormalisation compared to naive staggered quarks. The renormalisations are of similar size as for Wilson quarks.
