A bstract We apply the recently developed positivity bounds for particles with spin, applied away from forward limit, to low energy effective theories of massive spin-1 and spin-2 theories. For theories, we consider generic Proca EFT which arises at energies a heavy Higgs mechanism, special case charged Galileon is reorganized by symmetry. spin-2, Λ 5 gravity ‘ghost-free’ 3 Remarkably find that level 2-2 scattering, impose tunings generate structure. island derived in limit appears relatively stable against further bounds.
