A note on four-point functions of conformal operators in N=4 Super-Yang Mills

TL;DR

This paper investigates the first-order quantum corrections to four-point functions of specific conformal operators in N=4 Super-Yang Mills theory, revealing non-zero contributions that persist at large N_c.

Contribution

It provides the first explicit calculation showing non-vanishing first-order corrections to four-point functions in the large N_c limit.

Findings

First-order correction is non-zero and survives at large N_c.

The correction affects the understanding of correlators in N=4 SYM.

Results contribute to the study of conformal operator dynamics.

Abstract

We find that the first-order correction to the free-field result for the four-point function of the conformal operator $\tr(\phi^i\phi^j)$ is nonvanishing and survives in the limit $N_c \rar \infty$.
