Description
In this talk, I will review the on-shell method of constructing the operator bases of effective field theories. The first task is to eliminate all the operator redundancies and obtain an independent basis, which is accomplished by adopting the Young Tensor method. Then a special basis of operators organized by representations of the symmetry groups, named J-basis, is introduced. Applications of the J-basis will be demonstrated, including the loop level selection rules and the correspondence with the UV origins of the effective operators.
