الوصف: The QCD coupling, $\alpha_s$, has a critical role in Hadron collider studies of the Standard Model Effective Field Theory (SMEFT). Patterns of measurements can be modified by local contact operators in the SMEFT that change the measured value of a Lagrangian parameter from the case of the Standard Model; this is known as an input parameter correction. When such a parameter is then used to predict another observable, this modifies the relationship between observables. In this paper, we begin the process of characterizing $\alpha_s$ as an input parameter.
