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
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
Closed flux tubes in D = 2 + 1 SU(N ) gauge theories: dynamics and effective string description
A bstractWe extend our earlier calculations of the spectrum of closed flux tubes in SU(N ) gauge theories in 2 + 1 dimensions, with a focus on questions raised by recent theoretical progress on the
Thermodynamics of SU(N) Yang-Mills theories in 2 + 1 dimensions I — The confining phase
We compute the equation of state in the confining phase of SU(N) Yang-Mills theories with N = 2, 3, 4, 5 and 6 colors in 2 + 1 dimensions, via lattice simulations. At low enough temperatures, the
Yang-Mills glueballs as closed bosonic strings
A bstractWe put forward the Axionic String Ansatz (ASA), which provides a unified description for the worldsheet dynamics of confining strings in pure Yang-Mills theory both in D = 3 and D = 4
The spectrum of 2+1 dimensional Yang-Mills theory on a twisted spatial torus
A bstractWe compute and analyse the low-lying spectrum of 2+1 dimensional SU(N) Yang-Mills theory on a spatial torus of size l × l with twisted boundary conditions. This paper extends our previous
Large N scaling and factorization in SU(N) Yang–Mills gauge theory
The large N limit of SU(N )gauge theories is well understood in perturbation theory. Also non-perturbative lattice studies have yielded important positive evidence that ’t Hooft’s predictions are
Baryons under strong magnetic fields or in theories with space-dependent θ -term
Baryonic states are sufficiently complex to reveal physics that is hidden in the mesonic bound states. Using gauge/gravity correspondence we study analytically and numerically baryons in theories
