The existence of a "bonus" U(1) level-one Yangian symmetry of N=4 super-Yang-Mills has recently been proposed. We provide evidence for this proposal by constructing the BRST-invariant nonlocal charge in the pure spinor sigma model corresponding to this bonus level-one symmetry. We also construct analogous charges for bonus U(1) symmetries at all odd levels of the Yangian.

  1. Supersymmetry bicomplex of pure spinor AdS background

    hep-th 2026-06 unverdicted novelty 4.0

    Uses bicomplex spectral sequences from BRST and Lie cohomology to constrain the representation of AdS supersymmetry algebra for deformations of AdS5 × S5 and clarify ghost number three zero modes.
