QCD, monopoles on the Lattice and gauge invariance

Bonati, C. and D'Elia, M. and Giacomo, A. Di (2011) QCD, monopoles on the Lattice and gauge invariance. AIP conference proceedings, 1343 . pp. 215-217. ISSN 0094-243X

The number and the location of the monopoles observed on the lattice in QCD configurations happens to depend strongly on the choice of the gauge used to expose them, in contrast to the physical expectation that monopoles be gauge invariant objects. It is proved by use of the non abelian Bianchi identities (NABI) that monopoles are indeed gauge invariant, but the method used to detect them depends, in a controllable way, on the choice of the abelian projection. Numerical checks are presented.
