Semiclassical short strings in AdS_5 × S~5

摘要

In the short-string limit, we present results for the one-loop correction to the energy of string solutions in AdS_5 × S~5 that belong to a certain class. The computations are based on the observation that the fluctuation operators, just as for rigid spinning-string elliptic solutions, can be written in the single-gap Lamé form. Based on these computations, we reveal a remarkable universality of the expression for the energy of short semiclassical strings, which may help in better understanding the structure of the strongcoupling expansion of the anomalous dimensions of dual gauge theory operators.
