Develops spinor-helicity formalism generalizing partial wave unitarity bounds for multi-particle scattering and spin-2 or higher-spin theories.
A universal forward-scattering description in long-range theories makes partial-wave amplitudes well-defined single-scale objects computable order-by-order without spurious IR dependence.
HEFT admits two consistent power counting schemes, one with a single low-energy scale v and one with two scales v < f, each allowing systematic truncation of operators and amplitudes for any normalization choice.
