Spinning strings in AdS5×S5: 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×S5, 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).
