Spinning strings in AdS(4) x CP3 and quantum corrections

Abstract:

We derive the one-loop correction to the space-time energy of a folded string in AdS4 × C{double-struck}P{double-struck}3 carrying spin S in AdS4 and angular momentum J in C{double-struck}P{double-struck}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 Beth...
