Detecting the Higgs bosons of minimal supergravity with muon pairs

The prospects at the CERN LHC are investigated for the discovery via decays into muon pairs of neutral Higgs bosons in the minimal supergravity model. Promising results are found for the CP-odd pseudoscalar (A0) and the heavier CP-even scalar (H0) Higgs bosons at large tanβ≡v2/v1. For tanβ≳10 and 100 GeV ≲mA,mH≲ 550 GeV, the A0 and the H0 masses could be precisely reconstructed from the dimuon invariant mass.
