چکیده

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 explicitly. Good overall agreement with available lattice data is observed.

Physics from the lattice : glueballs in QCD ; topology ; SU ( N ) for all

1 1 Introduction In these lectures I will show, through three examples, how current lattice calculations are able to tell us interesting things about the continuum physics of non-Abelian gauge theories. My first topic concerns the glueball spectrum. The physics question here is: where, in the experimentally determined hadron spectrum, are the glueballs hiding? I will first summarise what lattic...

نظریه میدان ناجابه‌جایی و پارامترهای نقض لورنتس در QED

Non-commutative field theory as a theory including the Lorentz violation can be constructed in two different ways. In the first method, the non-commutative fields are the same as the ordinary ones while the gauge group is restricted to U(n). For example, the symmetry group of standard model in non-commutative space is U(3)×(2)×U(1) which can be reduced to SU(3)×SU(2)×U(1) by two appropriate spo...

The large N limit from the lattice ∗

A numerical study of the string tension and of the masses of the lowest-lying glueballs is performed in SU(N) gauge theories for 2 ≤ N ≤ 8 in D=3+1 and 2 ≤ N ≤ 6 in D=2+1. It is shown that for the string tension a smooth N → ∞ limit exists that depends only on the ’t Hooft coupling λ = gN . An extrapolation of the masses of the lightest glueballs to N = ∞ using a power series in 1/N shows that ...

Transverse Lattice Approach to Light-Front Hamiltonian QCD

We describe a non-perturbative procedure for solving from first principles the light-front Hamiltonian problem of SU(N) pure gauge theory in D spacetime dimensions (D ≥ 3), based on enforcing Lorentz covariance of observables. A transverse lattice regulator and colour-dielectric link fields are employed, together with an associated effective potential. We argue that the lightfront vacuum is nec...

Glueballs and the Pomeron *

We present our latest results on the glueball spectrum of SU (N) gauge theories in 2+1 dimensions for spins ranging from 0 to 6 inclusive, as well as preliminary results for SU (3) in 3+1 dimensions. Simple glueball models and the relation of the even-spin spectrum to the 'Pomeron' are discussed.
