Logarithmic corrections to higher twist scaling at strong coupling from AdS/CFT Original Research Article

We compute 1-loop correction image to the energy of folded string in image (carrying spin S in image and momentum J in image) using a “long string” approximation in which image. According to the AdS/CFT the function image should represent first subleading correction to strong coupling expansion of anomalous dimension of higher twist image sector operators of the form image. We show that image smoothly interpolates between the image regime (previously found in the image case) and the image regime (which is the leading correction to the thermodynamic limit on the spin chain side). This supports the universality of the image scaling. As in the previous work, we also find “non-analytic” corrections related to non-trivial 1-loop phase in the corresponding Bethe ansatz S-matrix.
