Abstract: (Elsevier)
The process e + e − → hA is used to search for the Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM), in the b b b b and τ + τ − b b 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/ c 2 , for tan β > 1.- electron positron: colliding beams
- electron positron: annihilation
- Higgs particle: electroproduction
- Higgs particle: pair production
- Z0: associated production
- supersymmetry
- Higgs particle: multiplet
- Higgs particle: hadronic decay
- Higgs particle: leptonic decay
- bottom: pair production
