Ambitwistor strings and reggeon amplitudes in N=4 SYM

Blog Article

We consider the description of reggeon amplitudes (Wilson lines arm tray for wheelchair form factors) in N=4 SYM within the framework of four dimensional ambitwistor string theory.The latter is used to derive scattering equations representation for reggeon amplitudes with multiple reggeized gluons present.It is shown, that corresponding tree-level string correlation function correctly reproduces previously obtained Grassmannian integral uri ease paw gel for cats representation of reggeon amplitudes in N=4 SYM.
