Vacuum 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 کاملConfinement and condensates without fine tuning in supergravity duals of gauge theories
We discuss a solution of the equations of motion of five-dimensional gauged type IIB supergravity that describes confining SU(N) gauge theories at large N and large ’t Hooft parameter. We prove confinement by computing the Wilson loop, and we show that our solution is generic, independent of most of the details of the theory. In particular, the Einstein-frame metric near its singularity, and th...
متن کاملVacuum condensates, effective gluon mass and color confinement in a new reformulation of QCD
We propose a new reformulation of Yang-Mills theory in which threeand four-gluon 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. Moreover, we set up a new 1/Nc color expansion in...
متن کاملTemperature Dependence of Gluon and Quark Condensates as from Linear Confinement
The gluon and quark condensates and their temperature dependence are investigated within QCD premises. The input for the former is a gauge invariant gg kernel made up of the direct (D), exchange (X) and contact(C) QCD interactions in the lowest order, but with the perturbative propagator k−2 replaced by a ‘nonperturbative k−4 form obtained via two differentiations: μ2∂2 m(m 2 + k2)−1, (μ a scal...
متن کاملStructure and Stability of Two-Dimensional Bose-Einstein Condensates Under Both Harmonic and Lattice Confinement
In this work, we study two-dimensional Bose–Einstein condensates confined by both a cylindrically symmetric harmonic potential and an optical lattice with equal periodicity in two orthogonal directions. We first identify the spectrum of the underlying two-dimensional linear problem through multiple-scale techniques. Then, we use the results obtained in the linear limit as a starting point for t...
