Spinning strings in AdS(5) x S**5: A Worldsheet perspective

We examine the leading Regge string states relevant for semi-classical spinning string solutions. Using elementary RNS techniques, quadratic terms in an effective Lagrangian are constructed which describe massive NSNS strings in a space-time with five-form flux. We then examine the specific case of AdS5 ×S 5 , finding the dependence of AdS “energy” (E0) on spin in AdS (S), spin on the sphere (J), and orbital angular momentum on the sphere (∇a∇ a ).
