Effective string description of confining flux tubes
read the original abstract
We review the current knowledge about the theoretical foundations of the effective string theory for confining flux tubes and the comparison of the predictions to pure gauge lattice data. A concise presentation of the effective string theory is provided, incorporating recent developments. We summarize the predictions for the spectrum and the profile/width of the flux tube and their comparison to lattice data. The review closes with a short summary of open questions for future research.

Confining Flux Tube in the Trace Deformed (2+1) Dimensional SU(2) Gauge Theory
In the reconfined phase of trace-deformed (2+1)D SU(2) gauge theory, Polyakov-loop data are accurately fit by the Polchinski-Yang rigid string while Nambu-Goto fails, with modified flux-tube width and a shift to first...

A more effective QCD string at colliders: Decay of excited strings and the worldsheet axion
Excitations of the worldsheet axion in an effective QCD string theory produce a phase-dependent effective tension that exponentially modifies the rate of string breaking via quark pair nucleation.
