Abstract: We consider the kinematics of the locally BPS super‐Wilson loop in N=4 super‐Yang‐Mills with scalar coupling from a twistorial point of view. We find that the kinematics can be described either as supersymmetrized pure spinors or as a point in the product of two super‐Grassmannian manifolds G2∣2(4∣4) × G2∣2(4∣4). In this description of the kinematics the scalar–scalar correlation function appearing in the one‐loop evaluation of the super‐Wilson loop can be neatly written as a sum of four superdeterminants.
