  The Next-to-Minimal Supersymmetric extension of the Standard Model (NMSSM)
with a Higgs boson of mass 125 GeV can be compatible with stop masses of order
of the electroweak scale, thereby reducing the degree of fine-tuning necessary
to achieve electroweak symmetry breaking. Moreover, in an attractive region of
the NMSSM parameter space, corresponding to the "alignment limit" in which one
of the neutral Higgs fields lies approximately in the same direction in field
space as the doublet Higgs vacuum expectation value, the observed Higgs boson
is predicted to have Standard-Model-like properties. We derive analytical
expressions for the alignment conditions and show that they point toward a more
natural region of parameter space for electroweak symmetry breaking, while
allowing for perturbativity of the theory up to the Planck scale. Moreover, the
alignment limit in the NMSSM leads to a well defined spectrum in the Higgs and
Higgsino sectors, and yields a rich and interesting Higgs boson phenomenology
that can be tested at the LHC. We discuss the most promising channels for
discovery and present several benchmark points for further study.
