Abstract In the three-dimensional $$\mathcal{N}$$ = 6 Chern-Simons matter (ABJM) theory, the integrand for the logarithm of the scattering amplitude admits a decomposition in terms of negative geometries, which implies that all the infrared divergenc

Abstract We study, in the context of the three-dimensional N $$ \mathcal{N} $$ = 6 Chern-Simons-matter (ABJM) theory, the infrared-finite functions that result from performing L − 1 loop integrations over the L-loop integrand of the logarithm of th

Abstract We study perturbative aspects of recently proposed integrated four-point correlators in N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills with all classical gauge groups using standard Feynman diagram computations. We argue that perturbative

Abstract In this paper, we introduce the momentum space amplituhedron for tree-level scattering amplitudes of ABJM theory. We demonstrate that the scattering amplitude can be identified as the canonical form on the space given by the product of posit

Abstract We present a compact formula in Mellin space for the four-point tree-level holographic correlators of chiral primary operators of arbitrary conformal weights in (2, 0) supergravity on AdS 3 × S 3, with two operators in tensor multiplet and

Abstract We study loop corrections to scattering amplitudes in the world-volume theory of a probe D3-brane, which is described by the supersymmetric Dirac-Born-Infeld theory. We show that the D3-brane loop superamplitudes can be obtained from the tre

Abstract Double-soft theorems, like its single-soft counterparts, arises from the underlying symmetry principles that constrain the interactions of massless particles. While single soft theorems can be derived in a non-perturbative fashion by employi

Soft theorems reveal the underlying symmetry of the theory and constrain the interaction of massless particles. In this thesis, we first derive single soft theorems in a non-perturbative fashion by employing current algebras. Then we expect
