We study eight fermion terms in the effective action of the ABJM model. We show the nonrenormalization of v2 terms. After classifying all the possible eight fermion structures, we show that N = 6 supersymmetry determines all these terms completely up to an overall constant. This confirms the one loop non-renormalization of v4 terms.

In the first half of this note, after briefly motivating and reviewing membrane field theories, we consider their BPS funnel solutions. We discuss some aspects of embedding M-theory fuzzy funnels in these theories. In the second half, we focus on ABJM theory and explain a test of AdS4/CFT3 based on integrability. We discuss a numerical mismatch at one loop in worldsheet perturbation theory and ...

We study, in the context of three-dimensional ${\cal N}=6$ Chern-Simons-matter (ABJM) theory, infrared-finite functions that result from performing $L-1$ loop integrations over $L$-loop integrand logarithm four-particle scattering amplitude. Our starting point are integrands obtained recently proposed all-loop projected amplituhedron for ABJM theory. Organizing them terms negative geometries en...
