Résumé

The process e⁺e^- → hA is used to search for the Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM), in the bb̄bb̄ and τ⁺τ^-bb̄ final states. The search is performed in the data collected by the ALEPH experiment at LEP, at centre-of-mass energies between 130 and 172 GeV and with a total luminosity of 27.2 pb^-1. No candidate events are found in either of the final states, in agreement with the expected background of 0.91 events from all Standard Model processes. Combined with searches for e⁺e^-→ hZ, this results in a 95% C.L. lower limit on the masses of both h and A of 62.5 GeV/c², for tan β > 1.

No candidate events are found in either of the final states, in agreement with the expected background of 0.91 events from all Standard Model processes.
