報告摘要:
Field space geometry has been fruitful in understanding many aspects of EFT, including basis-independent criteria for distinguishing HEFT vs. SMEFT, derivation of renormalization group equations and geometric soft theorem. We incorporate field space geometry in functional matching. A modified covariant derivative expansion method is proposed to calculate the functional traces while accommodating the covariance of the light subspace geometry. We apply this formalism to the non-linear sigma model and reproduce the effective theory more efficiently compared to other matching methods. A geometric universal one-loop effective action is also derived using geometrized EFT matching method.
