The saga of rooted staggered quarks
Michael Creutz
TL;DR
This paper reviews the historical debate over rooted staggered quarks in lattice QCD and argues that these simulations should be abandoned due to unresolved issues.
Contribution
It provides a historical perspective and a critical analysis leading to the conclusion that rooted staggered quark simulations are fundamentally flawed.
Findings
Rooted staggered quarks have unresolved theoretical issues.
The author advocates discarding these simulations.
Historical analysis supports the conclusion.
Abstract
I look at the rooting controversy from a historical point of view and review how I have come to the conclusion that these simulations involving staggered quarks must be discarded.
