Query: Natural NMSSM Higgs Bosons   We study the phenomenology of Higgs bosons close to 126 GeV within the scale
invariant unconstrained next-to-minimal supersymmetric Standard Model (NMSSM),
focusing on the regions of parameter space favoured by low fine-tuning
considerations, namely stop masses of order 400 GeV to 1 TeV and an effective
$\mu$ parameter between 100-200 GeV, with large (but perturbative) $\lambda$
and low $\tan \beta =$2-4. We perform scans over the above parameter space,
focusing on the observable Higgs cross sections into $\gamma \gamma$, $WW$,
$ZZ$, $bb$, $\tau \tau$ final states, and study the correlations between these
observables. We show that the $\gamma \gamma$ signal strength may be enhanced
up to a factor of about two not only due to the effect of singlet-doublet
mixing, which occurs more often when the 126 GeV Higgs boson is the
next-to-lightest CP-even one, but also due to light stops (and to a lesser
extent light chargino and charged Higgs loops). There may be also smaller
enhancements in the Higgs decay channels into $WW$, $ZZ$, correlated with the
$\gamma \gamma$ enhancement. However there is no such correlation observed
involving the Higgs decay channels into $bb$, $\tau \tau$. The requirement of
having perturbative couplings up to the GUT scale favours the interpretation of
the 126 GeV Higgs boson as being the second lightest NMSSM CP-even state, which
can decay into pairs of lighter neutralinos, CP-even or CP-odd Higgs bosons,
leading to characteristic signatures of the NMSSM. In a non-negligible part of
the parameter range the increase in the $\gamma\gamma$ rate is due to the
superposition of rates from nearly degenerate Higgs bosons. Resolving these
Higgs bosons would rule out the Standard Model, and provide evidence for the
NMSSM.
