Abstract

The process e+e− → hA is used to search for the Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM), in the bb and 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.
