SU(N ) gauge theories in 2+1 dimensions: glueball spectra and k-string tensions

  title={SU(N ) gauge theories in 2+1 dimensions: glueball spectra and k-string tensions},
  author={Andreas Athenodorou and M. Teper},
  journal={Journal of High Energy Physics},
A bstractWe calculate the low-lying glueball spectrum and various string tensions in SU(N ) lattice gauge theories in 2 + 1 dimensions, and extrapolate the results to the continuum limit. We do so for for the range N ∈ [2, 16] so as to control the N -dependence with a useful precision. We observe a number of striking near-degeneracies in the various JPC sectors of the glueball spectrum, in particular between C = + and C = − states. We calculate the string tensions of flux tubes in a number of… 

SO(N) gauge theories in 2 + 1 dimensions: glueball spectra and confinement

A bstractWe calculate the spectrum of light glueballs and the string tension in a number of SO(N) lattice gauge theories in 2+1 dimensions, with N in the range 3 ≤ N ≤ 16. After extrapolating to the

Strings in SU(N) gauge theories in 2+1 dimensions: beyond the fundamental representation

We calculate energies and tensions of closed k-strings in (2+1)-dimensional SU(N) gauge theories with N=4,5,6,8. When we study the dependence of the ground state energy on the string length, we find

On the spectrum and string tension of U(1) lattice gauge theory in 2 + 1 dimensions

A bstractWe calculate the low-lying spectra of glueballs and confining flux tubes in the U(1) lattice gauge theory in 2 + 1 dimensions. We see that up to modest lattice spacing corrections, the

Glueballs and k-strings in SU(N) gauge theories: calculations with improved operators

We test a variety of blocking and smearing algorithms for constructing glueball and string wave-functionals, and find some with much improved overlaps onto the lightest states. We use these

On the spectrum of closed k = 2 flux tubes in D = 2+1 SU(N) gauge theories

We calculate the energy spectrum of a k = 2 flux tube that is closed around a spatial torus, as a function of its length l. We do so for SU(4) and SU(5) gauge theories in 2 space dimensions. We find

Tensions and Lüscher terms for (2+1)-dimensional k-strings from holographic models

The leading term for the energy of a bound state of k-quarks and k-antiquarks is proportional to its separation L. These k-string configurations have a Luscher term associated with their quantum

Closed flux tubes and their string description in D=2+1 SU(N) gauge theories

We carry out lattice calculations of the spectrum of confining flux tubes that wind around a spatial torus of variable length l, in 2 + 1 dimensions. We compare the energies of the lowest ∼30 states



Glueball Spectra of SU(2) Gauge Theories in 3 and 4 Dimensions: A Comparison with the Isgur-Paton Flux Tube Model

We use the results of recent lattice calculations to obtain (part of) the mass spectrum of continuum SU(2) gauge theory in both 2+1 and 3+1 dimensions. We compare these spectra to the predictions of

This work extracts from the strong-coupling Hamiltonian lattice formulation of QCD a model for hadrons based on the use of quark and flux-tube degrees of freedom that can be tested by lattice Monte Carlo simulations.
