Higher Spin correlators

Triangular Seminar Alday Fernando (Oxford)

15:00 City U.
room AG07

I will discuss the three-point correlator of two protected scalar operators and one higher spin twist-two operator in N = 4 SYM, in the limit of large spin. This structure constant can be extracted from the OPE of the four-point correlator of protected scalar operators. Based on the OPE structure, symmetry arguments and intuition from the available perturbative results, it is possible to predict the structure constant at all loops in perturbation theory. Furthermore, this allows also to propose an expression for the all loops four-point correlator in a particular limit.
