19. Thermal monopoles in full QCD

Massimo D'Elia (University of Pisa and INFN)

Progress in the Confinement Problem

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.

13. Centre Vortex Structure of QCD-Vacuum Fields and Confinement

Prof. Derek Leinweber (CSSM, University of Adelaide)

Progress in the Confinement Problem

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...

12. Abelian monopoles of the Dirac type and color confinement in QCD

Tsuneo Suzuki (Research Center for Nuclear Physics, Osaka University)

Progress in the Confinement Problem

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...

14. Excited States of Isolated Fermions in the Higgs phase of gauge Higgs theories

Dr Kazue Matsuyama

11.11.2021, 12:30

Progress in the Confinement Problem

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.

9. Confinement, mass gap and gauge symmetry in the Yang-Mills theory

Kei-Ichi Kondo (Chiba University)

11.11.2021, 13:00

Progress in the Confinement Problem

I will discuss the possible relationship between confinement mechanism and the existence of mass gap in the Yang-Mills theory by respecting gauge symmetry.
