We review the bootstrap method for constructing six- and seven-particle amplitudes in planar $\mathcal{N}=4$ super Yang-Mills theory, by exploiting their analytic structure. We focus on two recently discovered properties which greatly simplify this construction at symbol and function level, respectively: the extended Steinmann relations, or equivalently cluster adjacency, and the coaction principle. We then demonstrate their power in determining the six-particle amplitude through six and seven loops in the NMHV and MHV sectors respectively, as well as the symbol of the NMHV seven-particle amplitude to four loops.

    One-cycle negative geometries in N=4 SYM have singularities only at z=-1, 0, and infinity to all loop orders.

  7. New Tools in the Landau Bootstrap

    hep-th 2026-07 conditional novelty 6.0

    Certain Feynman-integral discontinuities are 'non-repeating' (a second cut at the same singularity always vanishes), and certain 'Lefschetz-unique' discontinuities are independent of the order of prior cuts.
