Beschreibung:
<jats:p>Decomposition of SU(2) gauge field into monopole and monopoleless components is studied in SU(2) gluodynamics and in <jats:italic>QC</jats:italic><jats:sub>2</jats:sub><jats:italic>D</jats:italic> with zero and nonzero quark chemical potential after fixing MA gauge. For both components we calculate respective static potential and compare their sum with the nonabelian static potential. We demonstrate good agreement in the confinement phase and discuss the implications of our results.</jats:p>
