Abstract

The reactions e+e- --> hZ* and e+e- --> hA have been used to search for the neutral Higgs bosons h and A of the MSSM in the case where the CP-odd A is lighter than 2mμ, taking into account the large h → AA decay branching ratio. No signal was found in the data sample collected until the end of 1991 by the ALEPH experiment at LEP. For tan β ⩾, mA < 2mμ is excluded at 95% CL for any mh.
