We present a search of neutral Higgs bosons produced in association with b-quark(s) and decaying into b-quark pairs at the LHC data of 8 TeV (2012) recorded with the CMS detector. This process is a potential signature for heavy Higgs bosons as anticipated within the minimal supersymmetric model (MSSM), whose production is strongly enhanced for large values of the parameter tan beta. The signal of a Higgs boson would arise as an excess in the mass spectrum of the two jets with the highest transverse momentum. Multi-jet QCD events constitute the dominant background that is derived from data. In this presentation the first results for the analysis of 8 TeV data (2012) are shown.
