Morning session 7: Progress in the Confinement Problem
- Maxim Chernodub (University Of Tours)
We investigate the properties of thermal magnetic monopoles in the high temperature phase of QCD with 2+1 flavours and physical quark masses, with a particular focus on their condensation and its possible relation with other non-perturbative features of strongly interacting matter.
The non-trivial ground-state vacuum fields of QCD generate quark and gluon condensates and form the foundation of matter. Using modern visualization techniques, this presentation examines the microscopic structure of these fields. Of particular interest are the centre vortices identified within the ground-state fields of lattice QCD. This vortex structure is illustrated through renderings...
When non-Abelian gauge fields in SU(3) QCD have a line-singularity leading to non-commutativity with respect to successive partial-derivative operations, the non-Abelian Bianchi identity is violated. The violation as an operator is shown to be equivalent to violation of the Abelian-like Bianchi identities. Then there appear eight Abelian-like conserved magnetic monopoles of the Dirac type in...
I present numerical evidence that the gauge+Higgs fields surrounding isolated charged fermions, in a variety of gauge Higgs theories, have a spectrum of localized excited states. This would appear as a mass spectrum of “elementary” fermions, taken to be static for simplicity.
I will discuss the possible relationship between confinement mechanism and the existence of mass gap in the Yang-Mills theory by respecting gauge symmetry.
