Search for a very light CP-odd neutral Higgs boson of the MSSM
Description
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. (orig.)
