Resumo

The existence of a "bonus" U(1) level- one Yangian symmetry of N= 4 superYang- 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. (AU)
