Quantum corrections to spinning strings in AdS(5) x S(5) and Bethe ansatz : a comparative study.

Schäfer-Nameki, S. and Zamaklar, M. and Zarembo, K. (2005) 'Quantum corrections to spinning strings in AdS(5) x S(5) and Bethe ansatz : a comparative study.', Journal of high energy physics., 2005 (09). 051.


We analyze quantum corrections to rigid spinning strings in AdS5 × S5. The one-loop worldsheet quantum correction to the string energy is compared to the finite-size correction from the quantum string Bethe ansatz. Expanding the summands of the string theory energy shift in the parameter 1/2 and subsequently resumming them yields a divergent result. However, upon zeta-function regularisation these results agree with the Bethe ansatz in the first three orders. We also perform an analogous computation in the limit of large winding number, which results in a disagreement with the string Bethe ansatz prediction. A similar mismatch is observed numerically. We comment on the possible origin of this discrepancy.
