We show that there is a special choice of parameters for which the galileon theory is invariant under an enhanced shift symmetry whose non-linear part is quadratic in the coordinates. This symmetry fixes the theory to be equivalent to one with only even powers of the field, with no free coefficients, and accounts for the improved soft limit behavior observed in the quartic galileon S-matrix.

  1. Diffeomorphic Scalar Duality

    hep-th 2026-06 unverdicted novelty 7.0

    Every local scalar EFT admits a duality to an infinite class of other scalar theories via field-dependent diffeomorphisms preserving the S-matrix, extending to gravity in Einstein-Cartan formalism.

    Nonlocal Källén-Lehmann spectral densities in the Higgs sector yield exponentially suppressed scattering amplitudes above Λ_NL and suppress the real part of the Higgs self-energy at p² ~ -Λ²_NL, solving the hierarchy ...
