Description
Massive field EFTs are widely used in particle physics, but how to construct massive field operators efficiently remains a challenge. We propose a general theory to solve this problem based on the scattering amplitude theory. We find that the complete set of EFT bases can be systematically constructed using the Lorentz subgroup SU(2) and global symmetry U(N), where N represents the number of external particles. After reducing their dimension to the lowest, the resulting amplitude bases can be mapped into operator bases of massive fields. With this theory, all operator bases of massive fields with any spins can be constructed by computer programs automatically.
