Query: Higgs Couplings and Naturalness   Many extensions of the Standard Model postulate the existence of new weakly
coupled particles, the top partners, at or below the TeV scale. The role of the
top partners is to cancel the quadratic divergence in the Higgs mass parameter
due to top loops. We point out the generic correlation between naturalness (the
degree of fine-tuning required to obtain the observed electroweak scale), and
the size of top partner loop contributions to Higgs couplings to photons and
gluons. If the fine-tuning is required to be at or below a certain level, a
model-independent lower bound on the deviations of these Higgs couplings from
the Standard Model can be placed (assuming no cancellations between
contributions from various sources). Conversely, if a precise measurement of
the Higgs couplings shows no deviation from the Standard Model, a certain
amount of fine-tuning would be required. We quantify this connection, and argue
that a measurement of the Higgs couplings at the per-cent level would provide a
serious and robust test of naturalness.
