Studying glueball masses in non-Abelian LGT with the LW algorithm

We address a study of glueball masses in the confining regime of SU(2) in D = 3 using an algo-rithm 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 gen-eralises 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
