Abstract We study the four-point correlator O 2 O 2 DD $$ \left\langle {\mathcal{O}}_2{\mathcal{O}}_2\mathcal{DD}\right\rangle $$ in N $$ \mathcal{N} $$ = 4 super Yang-Mills theory (SYM) with SU(N) gauge group, where O 2 $$ {\mathcal{O}}_2 $$ represe

Abstract Integrated correlation functions in N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills theory with gauge group SU(N) can be expressed in terms of the localised S 4 partition function, Z N , deformed by a mass m. Two such cases are C N = Im τ

Abstract Recently it has been shown that Bern-Carrasco-Johansson (BCJ) numerators of colour-kinematic duality for tree-level scattering amplitudes in Yang-Mills theory (coupled with scalars) can be determined using a quasi-shuffle Hopf algebra. In th

Abstract We recently proved that, when integrating out the spacetime dependence with a certain integration measure, four-point correlators O 2 O 2 O p i O p i $$ \left\langle {\mathcal{O}}_2{\mathcal{O}}_2{\mathcal{O}}_p^{(i)}{\mathcal{O}}_p^{(i)}\ri

Abstract The use of supersymmetric localisation has recently led to modular covariant expressions for certain integrated correlators of half-BPS operators in N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills theory with a general classical gauge grou

Abstract It was recently proposed that the kinematic algebra featuring in the colour-kinematics duality for scattering amplitudes in heavy-mass effective field theory (HEFT) and Yang-Mills theory is a quasi-shuffle Hopf algebra. The associated fusion

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 The exact expressions for integrated maximal U(1) Y violating (MUV) n-point correlators in SU(N) N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills theory are determined. The analysis generalises previous results on the integrated correlator
