Query: Convergent Bayesian Global Fits of 4D Composite Higgs Models   Models in which the Higgs boson is a composite pseudo-Nambu-Goldstone boson
offer attractive solutions to the Higgs mass naturalness problem. We consider
three such models based on the minimal $SO(5) \rightarrow SO(4)$ symmetry
breaking pattern, and perform convergent global fits on the models under a
Bayesian framework in order to find the regions of their parameter spaces that
best fit a wide range of constraints, including recent Higgs measurements. We
use a novel technique to analyse the fine-tuning of the models, quantifying the
tuning as the Kullback-Leibler divergence from the prior to the posterior
probability on the parameter space. Each model is found to be able to satisfy
all constraints at the $3\sigma$ level simultaneously. As a by-product of the
fits, we analyse the collider phenomenology of our models in these viable
regions. In two of the three models, we find that the $g g \rightarrow H
\rightarrow \gamma \gamma$ cross section is less than ${\sim}90$% that
predicted by the SM, which is already in slight tension with experiment and
could potentially be ruled out in the future high-luminosity run of the LHC. In
addition, the lightest fermions $F$ arising from the new strong dynamics in
these models are seen in general to lie above ${\sim}1.1$ TeV, with the $F
\rightarrow tW^{+}$ and $F \rightarrow \bar{b}W^{+}$ decays offering
particularly promising channels for probing these models in future collider
searches.
