摘要: Abstract Using the AdS/CFT correspondence in a confining background and worldline formalism of gauge field theories, we compute scattering amplitudes with an exchange quark antiquark t-channel corresponding to reggeon exchange. It requires going beyond eikonal approximation, which was used when studying pomeron The wordline path integral is evaluated through determination minimal surfaces their boundaries by saddle-point method at large coupling g2Nc. We find Regge behaviour linear trajectories. slope related q static potential four times obtained same framework. A contribution intercept, Luscher term, comes from fluctuations around surface.
