In this paper, we work with 16 different single scalar particle extensions ofthe Standard Model. We present the sets of dimension-6 effective operators andthe associated Wilson coefficients as functions of model parameters afterintegrating out the heavy scalars up to 1-loop, including the heavy-lightmixing, for each such scenario. Using the correspondence between the effectiveoperators and the observables at electroweak scale, and employing Bayesianstatistics, we compute the allowed ranges of new physics parameters that arefurther translated and depicted in 2-dimensional Wilson coefficient space inthe light of the latest CMS and ATLAS data up to $137 \text{ fb}^{-1}$ and$139\text{ fb}^{-1}$, respectively. We also adjudge the status of those newphysics extensions that offer similar sets of relevant effective operators. Inaddition, we provide a model-independent fit of $23$ Standard Model effectivefield theory Wilson coefficients using electroweak precision observables,single and di-Higgs data as well as kinematic distributions of di-bosonproduction.
