A bstract We propose a model for the QCD axion which is realized through a coupling of the
Peccei-Quinn scalar field to magnetically charged fermions at high energies. We show that …

We study, by means of numerical lattice simulations, the properties of the reconfinement
phase transition taking place in trace deformed SU (3) Yang-Mills theory defined on R 3× S …

We investigate the connection between color confinement and thermal Abelian monopoles
populating the deconfined phase of SU (2) Yang-Mills theory, by studying how the statistical …

If non-Abelian gauge fields in SU (3) QCD have a line-singularity leading to
noncommutativity with respect to successive partial-derivative operations, the non-Abelian …

We discover the origin of the pathologies of the disorder parameter used in previous papers
to detect dual superconductivity of QCD vacuum, and we remove them by defining an …

We discuss and propose a proper extension of the Abelian projection based on the Maximal
Abelian Gauge to SU (N) gauge theories. Based on that, we investigate the properties of …

A new scheme for color confinement in QCD due to violation of the non-Abelian Bianchi
identities is proposed. The violation of the non-Abelian Bianchi identities (VNABI) J μ is …

Non-Abelian gauge fields having a line-singularity of the Dirac type lead us to violation of
the non-Abelian Bianchi identity. The violation as an operator is equivalent to violation of …

Monopolelike objects have been identified in multiple lattice studies, and there is now a
significant amount of literature on their importance in phenomenology. Some analytic …

A bstract In this work we study the topological properties of the G 2 lattice gauge theory by
means of Monte Carlo simulations. We focus on the behaviour of topological quantities …
