We derive the one-loop correction to the space-time energy of a folded string in AdS4 × 3 carrying spin S in AdS4 and angular momentum J in 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 −(5log 2)/(2π). This value appears to be in conflict with the prediction from the recently conjectured all-loop Bethe ansatz.
