Abstract Recent lattice results strongly support the Axionic String Ansatz (ASA) for quantum numbers of glueballs in 3D Yang-Mills theory. The ASA treats glueballs as closed bosonic strings. The corresponding worldsheet theory is a deformation of the minimal Nambu-Goto theory. In order to understand better the ASA strings and as a first step towards a perturbative calculation of the glueball mass splittings we compare the ASA spectrum to the closed effective string theory. Namely, we model… 
Yang-Baxter deformations of the flat space string
We define integrability preserving Yang-Baxter deformations of symmetric space sigma models with non-semi-simple symmetry group, in particular the flat space string, using only the essential structures

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
Glueball spins in D = 3 Yang-Mills
Abstract We determine spins of more than 100 low lying glueball states in D = 2 + 1 dimensional SU (4) gluodynamics by a lattice calculation. We go up to J = 8 in the spin value. We compare the
Glueballs as rotating folded closed strings
A bstractIn previous papers [1, 2] we argued that mesons and baryons can be described as rotating open strings in holographic backgrounds. Now we turn to closed strings, which should be the duals of
Quantizing the rotating string with massive endpoints
A bstractWe compute leading order quantum corrections to the Regge trajectory of a rotating string with massive endpoints using semiclassical methods. We expand the bosonic string action around a
String theory of the Regge intercept.
Using the Polchinski-Strominger effective string theory in the covariant gauge, we compute the mass of a rotating string in D dimensions with large angular momenta J, in one or two planes, in fixed
SU(N ) gauge theories in 2+1 dimensions: glueball spectra and k-string tensions
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
The glueball spectrum of SU(3) gauge theory in 3 + 1 dimensions
We calculate the low-lying glueball spectrum of the SU(3) lattice gauge theory in 3+1 dimensions for the range of beta up to beta=6.50 using the standard plaquette action. We do so for states in all
On the quantization of folded strings in non-critical dimensions
Classical rotating closed string are folded strings. At the folding points the scalar curvature associated with the induced metric diverges. As a consequence one cannot properly quantize the
Towards a theory of the QCD string
A bstractWe construct a new model of four-dimensional relativistic strings with integrable dynamics on the worldsheet. In addition to translational modes this model contains a single massless
QCD β -function on the string worldsheet
We consider confining strings in pure gluodynamics and its extensions with adjoint (s)quarks. We argue that there is a direct map between the set of bulk fields and the worldsheet degrees of freedom.
