Abstract

We derive the one‐loop correction to the space‐time energy of a folded string in AdS~4~ × CP^3^ carrying spin S in AdS~4~ and angular momentum J in CP^3^ in the long string approximation. From this general result in the limit J log S we obtain the one‐loop correction to the cusp anomalous dimension which turns out to be –(5 log 2)/(2π). This value appears to be in conflict with the prediction from the recently conjectured all‐loop Bethe ansatz.

## Abstract We review peculiar features of type IIA string theory compactified on AdS~4~ × CP^3^ superspace, in particular, the structure of the Green–Schwarz action, issues with fixing its kappa–symmetry, classical integrability and the string instanton on CP^3^.
