Section a : Confinement Mechanism , Flux Tubes and Strings
نویسنده
چکیده
An overview of some issues discussed is given, including the following ones: (i) the mechanism of confinement, (ii) the structure of the string, (iii) nonperturbative glue in vacuum and hadrons, and (v) quark-hadron duality. In doing so I try to indicate issues important for JLab. Finally I discuss another issue debated during this conference, namely (vi) whether one can use some common effective potential for description of various hadrons, using heavy quarkonia as

Confining flux tubes in a current algebra approach.
We describe flux tubes and their interactions in a low energy sigma model induced by SU(Nf ) → SO(Nf ) flavor symmetry breaking in SO(Nc) QCD. Unlike standard QCD, this model allows gauge confinement to manifest itself in the low energy theory, which has unscreened spinor color sources and global Z2 flux tubes. We construct the flux tubes and show how they mediate the confinement of spinor sour...
متن کاملNon-Abelian Confinement via Abelian Flux Tubes in Softly Broken N = 2 SUSY QCD
We study confinement in softly broken N = 2 SUSY QCD with gauge group SU(Nc) and Nf hypermultiplets of fundamental matter (quarks) when the Coulomb branch is lifted by small mass of adjoint matter. Concentrating mostly on the theory with SU(3) gauge group we discuss the N = 1 vacua which arise in the weak coupling at large values of quark masses and study flux tubes and monopole confinement in ...
متن کاملFlux tubes in three-dimensional lattice gauge theories.
Measurements of flux-tubes generated by sources in different representations of SU(2) and U(1) lattice gauge theory in three dimensions are reported. Heavy “quarks” are considered in three representations of SU(2): fundamental (j = 1/2), adjoint (j = 1), and quartet (j = 3/2). Wilson loops are used to introduce a static quark-antiquark (QjQj) pair. Several attributes of the fields generated by ...
متن کاملFlux Tubes on Higgs Branches in SUSY Gauge Theories
We study flux tubes on Higgs branches with curved geometry in supersymmetric gauge theories. As a first example we consider N=1 QED with one flavor of charges and with Higgs branch curved by adding a FayetIliopoulos (FI) term. We show that in a generic vacuum on the Higgs branch flux tubes exist but become “thick”. Their internal structure in the plane orthogonal to the string is determined by ...
متن کاملNon-Abelian Meissner Effect in Yang–Mills Theories at Weak Coupling
We present a weak-coupling Yang–Mills model supporting non-Abelian magnetic flux tubes and non-Abelian confined magnetic monopoles. In the dual description the magnetic flux tubes are prototypes of the QCD strings. Dualizing the confined magnetic monopoles we get gluelumps which convert a “QCD string” in the excited state to that in the ground state. Introducing a mass parameter m we discover a...
