Confinement in Light-front Qcd
Numerical results for the calculation of the (rest-frame) QQ̄ potential, for light-front quantized QCD2+1 on a ⊥ lattice are presented. Both in the longitudinal as well as the ⊥ spatial directions one obtains linear confinement. The resulting potential is almost rotational symmetric. Light-front (LF) quantization is the most physical approach to calculating parton distributions on the basis of Q...
متن کاملConfinement, Spin, and Qcd ∗
The experimental and theoretical evidence relating spin dependence and long range confinement is reviewed. One of the simplest confinement ideas, the dynamic electric flux tube picture of Buchmüller, can be exploited to yield a complete effective Hamiltonian. In addition to pure Thomas spin-orbit splitting the other relativistic corrections are calculated. It is shown that our effective Hamilto...
متن کاملLinear Confinement and AdS/QCD
In a theory with linear confinement, such as QCD, the masses squared, mn,S, of mesons with high spin S or high radial excitation number n are expected, from semiclassical arguments, to grow linearly with S and n. We show that this translates into a strong constraint on the infrared behavior of a putative 5-dimensional theory holographically dual to QCD (AdS/QCD). In the simplest model which obe...
متن کاملConfinement and the Supercritical Pomeron in Qcd
Deep-inelastic diffractive scaling violations have provided fundamental insight into the QCD pomeron, suggesting a single gluon inner structure rather than that of a perturbative two-gluon bound state. This paper derives a highenergy, transverse momentum cut-off, confining solution of QCD. The pomeron, in first approximation, is a single reggeized gluon plus a “wee parton” component that compen...
متن کاملDynamical Confinement in Bosonized Qcd 2 *
In the bosonized version of two dimensional theories non trivial boundary conditions (topology) play a crucial role. They are inevitable if one wants to describe non singlet states. In abelian bosonization, color is the charge of a topological current in terms of a non-linear meson field. We show that confinement appears as the dynamical collapse of the topology associated with its non trivial ...
