Description
In this blackboard talk I will review the formalism of effective string theory and its generic predictions, and why it breaks down in theories like QED_3 (in UV completions that lead to confinement), for which the mass gap is well below the scale of the confining string tension. A similar breakdown appears for solitonic strings. I will then describe an alternative method to perform computations in such theories, and the results for some properties of strings in QED_3 that differ from standard effective string theory. Based on 2412.01313 written in collaboration with Barel and Sheaffer.
