Gluelump spectrum in the QCD string model
نویسنده
چکیده
Spectrum of gluons in the adjoint source field is computed analytically using the QCD string Hamiltonian, containing only one parameter – string tension, fixed by meson and glueball spectrum. Spin splitting is shown to be small. A good agreement is observed with spa-cially generated gluelump states measured on the lattice. Important role of gluelumps defining the behaviour of field-strength correlators is stressed and correspondence with earlier computations of the latter is established.

Adjoint “quarks” on coarse anisotropic lattices: Implications for string breaking in full QCD
A detailed study is made of four dimensional SU(2) gauge theory with static adjoint “quarks” in the context of string breaking. A tadpole-improved action is used to do simulations on lattices with coarse spatial spacings as, allowing the static potential to be probed at large separations at a dramatically reduced computational cost. Highly anisotropic lattices are used, with fine temporal spaci...

Results from a comprehensive new analysis on the excitation spectrum of the QCD string are presented. A rapid onset of string formation is observed in the spectrum on a length scale of 2 fm, with Dirichlet boundary conditions. The crossover from the short distance spectrum towards string excitations and an observed fine structure in the 1–3 fm range are related to effective string theory. The d...
متن کاملGlueballs, Gluerings and Gluestars in the D = 2 + 1 Su(n) Gauge Theory
The 3d gluodynamics which governs the large T quark gluon plasma is studied in the framework of the field correlator method. Field cor-relators and spacial string tension are derived through the gluelump Green's functions. The glueball spectrum is calculated both in C = −1 as well as in C = +1 sectors, and multigluon bound states in the form of " gluon rings " and " gluon stars " are computed e...
متن کاملXX Conference – Location, Date-start- Date-end, Year The pomeron conjecture and two gluon glueballs
In this talk the pomeron conjecture is reviewed and constituent gluon models are derived. In a simple two-gluon glueball spectrum the pomeron trajectory and the daughter trajectories are computed. The open problems of two-gluon glueballs are discussed, including transversality and Yang’s theorem, the spin tensor interactions, the structure of the string and decays. The related systems of charme...
متن کاملMass spectrum of heavy hybrid mesons in the QCD string model
Using adiabatic hybrid meson potentials calculated in the QCD string model, the mass spectrum of heavy hybrid mesons is calculated in Born-Oppenheimer approximation within the accuracy of 100 MeV. INTRODUCTION A phenomenon of valence glue is very interesting from theoretical point of view, since it is directly related to the phenomenon of confinement. It is well known that states consisting of ...
