Description
We present a novel framework for effective field theory (EFT) matching that leverages generalized unitarity cuts to generate one-loop integrands directly from tree-level amplitudes. This on-shell approach effectively eliminates contributions from unphysical degrees of freedom. Furthermore, by extending the on-shell prescription to d dimensions, our method recovers the rational terms essentially in matching process. The resulting framework achieves a precise mapping of ultraviolet amplitudes onto EFT Wilson coefficients, and seamlessly integrates with on-shell EFT operator bases. This work offers a promising pathway toward more efficient and systematic EFT calculations with broad applications in high-energy physics.
