摘要:We address a study of glueball masses in the confining regime of SU(2) in D = 3 using an algorithm
inspired by the multi-level scheme. Our method, which exploits the locality of the action to
achieve high precision results, is based on a technique already used for compact QED, and generalises
it to the non-Abelian case. We discuss the main features of this method, in comparison
with other algorithms that have been used in similar studies.
