Abstract
We present results from a state-of-the-art fit of electroweak precision observables and Higgs-boson signal-strength measurements performed using 7 and 8 TeV data from the Large Hadron Collider. Based on the HEPfit package, our study updates the traditional fit of electroweak precision observables and extends it to include Higgs-boson measurements. As a result we obtain constraints on new physics corrections to both electroweak observables and Higgs-boson couplings. We present the projected accuracy of the fit taking into account the expected sensitivities at future colliders.
Highlights
NP effects on both EWPO and Higgs-boson couplings based on an effective-field-theory approach will be presented in a forthcoming paper [8]

Exploiting the Markov-Chain Monte-Carlo implementation provided in the Bayesian Analysis Toolkit (BAT) [11], HEPfit can be used as a standalone program to perform Bayesian statistical analyses
Summary
The HEPfit package is a general tool to combine direct and indirect constraints on the Standard Model and its extensions, available under the GNU General Public License (GPL) [2]. The HEPfit code can be extended to include new observables and NP models which can be added to the main core as external modules. Exploiting the Markov-Chain Monte-Carlo implementation provided in the Bayesian Analysis Toolkit (BAT) [11], HEPfit can be used as a standalone program to perform Bayesian statistical analyses. It can be used in library mode to compute observables in any implemented model, allowing for phenomenological analyses in any statistical framework. The interested reader can find more details on HEPfit in refs. In this paper we use HEPfit to perform a Bayesian statistical analysis of EWPO and Higgs-boson observables in the SM and beyond. The EWPO results have been successfully validated against ZFITTER [12]
