… It is an interesting question to investigate whether QCD corresponds to a string theory, and
if so, what string theory reproduces QCD. An important tool in this kind of investigation is the …

We 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 …

… long QCD strings appear to be well described by the Nambu-Goto area action. But quantization
of short, highly quantum QCD strings… The connection of gauge theory with string theory is …

… Here we will proceed in a different way, motivated mainly by the observation that QCD string
theory is probably very different from traditional string theory. In particular, the QCD string …

… We demonstrate that such strings behave as superconducting strings, and we estimate
the maximum current that they can carry. Thus, QCD strings at high density may affect the …

… discuss QCD strings in the d = 3 spatial dimension, corresponding to the mixed phase of
QCD, we also would like to keep in mind that at time zero the “prompt” near-critical string balls …

… and string tension … QCD vacuum continues with vigorous effort. Our view is that the relevant
properties of the underlying effective QCD string theory, whether it emerges from strictly string …

… The quantum properties of a helixlike shaped QCD string are studied … string fragmentation
process describe the mass hierarchy of light pseudoscalar mesons. The quantized helix string …

… several arguments originating both in string theory and QCD as we understand it, that will
help us analyse in more detail the structure of the string theory dual of QCD. We will see that …

… somehow need to construct a curved string background which is such that the U-shaped
string has a long horizontal segment with an effective non-zero string tension. For the AdS5 × …
