Results are presented on the discovery potential for MSSM neutral Higgs bosons in the mh-max scenario. The region of large cosβ, between 15 and 50, and mass between ≈95 and 130 GeV is considered in the framework of the ATLAS experiment at the large hadron collider (LHC), for a centre-of-mass energy 
= 14 TeV. This parameter region is not fully covered by the present data either from LEP or from Tevatron. The h/A bosons, supposed to be very close in mass in that region, are studied in the channel h/A→μ+μ- accompanied by two b-jets. The study includes a method to control the most copious background, Z→μ+μ- accompanied by two b-jets. A possible contribution of the H boson to the signal is also considered.
