Query: Correlating uncertainties in global analyses within SMEFT matters   We investigate the impact of correlations between (theoretical and
experimental) uncertainties on multi-experiment, multi-observable analyses
within the Standard Model Effective Field Theory (SMEFT). To do so, we perform
a model-independent analysis of $t$-channel single top-quark production and
top-quark decay data from ATLAS, CMS, CDF and D0. We show quantitatively how
the fit changes when different experimental or theoretical correlations are
assumed. Scaling down statistical uncertainties according to the luminosities
of future colliders with $300 \, {\rm fb}^{-1}$ and higher, we find that this
effect becomes a matter of life and death: assuming no correlations returns a
fit in agreement with the Standard Model while a 'best guess'-ansatz taking
into account correlations would observe new physics. At the same time,
modelling the impact of higher order SMEFT-corrections the latter turn out to
be a subleading source of uncertainty only.
