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 space-time dimensions. The ASA is motivated by the excitation spectrum of long confining strings, as measured on a lattice, and by recently constructed integrable axionic non-critical string models. According to the ASA, pure gluodynamics in 3D is described by a non-critical bosonic string theory without… 

3D Yang-Mills glueballs vs closed effective strings

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

From QCD Strings to WZW

A bstractAccording to the Axionic String Ansatz (ASA) confining flux tubes in pure gluodynamics are in the same equivalence class as a new family of integrable non-critical strings, called axionic

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

A simple worldsheet black hole

A bstractWe study worldsheet theory of confining strings in two-dimensional massive adjoint QCD. Similarly to confining strings in higher dimensions this theory exhibits a non-trivial S-matrix

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.

Fine corrections in the effective string describing SU(2) Yang-Mills theory in three dimensions

Abstract We present a study of the effective string that describes the infrared dynamics of SU(2) Yang-Mills theory in three dimensions. By combining high-precision lattice simulation results for

Excited mesons, baryons, glueballs and tetraquarks: predictions of the Holography Inspired Stringy Hadron model

In this note we collect and summarize the predictions of the Holography Inspired Stringy Hadron (HISH) model. Following a brief review of the model, we list the masses and widths of predicted excited

Confining strings, infinite statistics, and integrability

We study confining strings in massive adjoint two-dimensional chromodynamics. Off-shell, as a consequence of zigzag formation, the resulting worldsheet theory provides a non-trivial dynamical

Asymptotic fragility, near AdS2 holography and TT¯$$ T\overline{T} $$

A bstractWe present the exact solution for the scattering problem in the flat space Jackiw-Teitelboim (JT) gravity coupled to an arbitrary quantum field theory. JT gravity results in a gravitational

Undressing confining flux tubes with TT¯

Lattice QCD simulations provide crucial information about the worldsheet dynamics of confining strings (flux tubes). An accurate extraction of the worldsheet $S$-matrix from lattice spectra requires

Looking for integrability on the worldsheet of confining strings

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

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

Corrections to Nambu-Goto energy levels from the effective string action

The effective action on long strings, such as confining strings in pure Yang-Mills theories, is well-approximated by the Nambu-Goto action, but this action cannot be exact. The leading possible

String excitation energies in SU(N) gauge theories beyond the free-string approximation

In the presence of a static quark--antiquark pair, the spectrum of the low-lying states in SU($N$) gauge theories is discrete and likely to be described, at large quark separations $r$, by an
