abstract = {A search for a light neutral Higgs boson decaying into a
pair of b quarks is presented. Such Higgs bosons are
predicted by certain scenarios of the Next-to-Minimal
Supersymmetric Standard Model (NMSSM), whose Higgs sector
has two complex Higgs doublets and an additional Higgs
singlet. If the lightest Higgs boson has a sizeable singlet
admixture, it may have escaped detection in previous
searches at LEP, Tevatron,and LHC, but could be produced at
a substantial rate in neutralino decays within
supersymmetric cascades. This analysis is the first search
for Higgs bosons in the mass range below 100 GeV in the
b-quark final state at the LHC. It uses a data sample
corresponding to an integrated luminosity of 19.7 fb−1,
which has been recorded by the CMS experiment in 2012 at a
centre-of-mass energy of 8 TeV. Events with a pair of
b-tagged jets, at least two very energetic jets, and large
missing energy are selected. The invariant mass of the two
selected b-tagged jets is used to extract the signal. The
observed invariant-mass spectrum is in good agreement with
the background expected from Standard-Model processes. The
results are interpreted in terms of cross-section limits and
within light-Higgs-boson scenarios of the NMSSM. The
modified P4 benchmark scenario of the NMSSM is excluded by
this analysis.},
