A Dynamical Model of Color Confinement *
نویسندگان
چکیده
A dynamical model of confinement based on a transport theoretical description of the Friedberg-Lee model is extended to explicit color degrees of freedom. The string tension is reproduced by an adiabatic string formation from the nucleon ground state. Color isovector oscillation modes of a q ¯ q-system are investigated for a wide range of relative q ¯ q-momenta and the dynamical impact of color confinement on the quark motion is shown.

Ja n 19 94 Color Confinement , Quark Pair Creation and Dynamical Chiral - Symmetry Breaking in the Dual Ginzburg - Landau Theory
We study the color confinement, the q-¯ q pair creation and the dynamical chiral-symmetry breaking of nonperturbative QCD by using the dual Ginzburg-Landau theory, where QCD-monopole condensation plays an essential role on the nonper-turbative dynamics in the infrared region. As a result of the dual Meissner effect, the linear static quark potential, which characterizes the quark confinement, i...
متن کاملVacuum Condensates, Effective Gluon Mass and Color Confinement
We propose a new reformulation of Yang-Mills theory in which threeand fourgluon self-interactions are eliminated at the price of introducing a sufficient number of auxiliary fields. We discuss the validity of this reformulation in the possible applications such as dynamical gluon mass generation, color confinement and glueball mass calculation. We emphasize the transverse-gluon pair condensatio...
متن کاملColor Confinement and Dynamical Effect of Light Quarks in the Dual Ginzburg-landau Theory
We study nonperturbative features of QCD using the dual Ginzburg-Landau theory. The color confinement is realized through the dual Higgs mechanism, which is brought by QCD-monopole condensation. We investigate the infrared screening effect on the color confinement due to the light-quark pair creation. By solving the Schwinger-Dyson equation, we find that the dynamical chiral-symmetry breaking i...
متن کاملCalculating charge radius for proton with hyper central interacting color potential
An improved M.I.T. bag model with hyper central interaction is used to calculate the charge radius for proton containing u and d quarks. We present a theoretical approach to the internal structure of three-body hyper central interacting quarks in a proton, in which we take proton as a bag. We discuss a few of results obtained using a six-dimension potential, which is attractive for small separa...
متن کاملColor Confinement in Perturbation Theory from a Topological Model
Color confinement by the mechanism of Kugo and Ojima can treat confinement of any quantized color carrying fields including dynamical quarks. However, the non-perturbative condition for this confinement has been known to be satisfied only in the pure-gauge model (PGM), which is a topological model without physical degrees of freedom. Here we analyze the Yang-Mills theory by adding physical degr...
