Searches for neutral Higgs bosons in e+e− collisions at centre-of-mass energies from 192 to 202 GeV

Searchesfor neutral Higgs bosonsare performed with the 237 pb^-1 of data collected in 1999 by the ALEPHdetector at LEP, for centre-of-mass energies between 191.6 and 201.6 GeV. These searchesapply to Higgs bosonswithin the context of the Standard Modeland its minimal supersymmetric extension (MSSM) as well as to invisiblydecaying Higgs bosons. No evidence of a signal is seen. A lower limit on the mass of the Standard Model Higgs bosonof 107.7 GeV/c^2 at 95% confidence level is set. In the MSSM, lower limits of 91.2 and 91.6 GeV/c^2 are derived for the masses of the neutral Higgs bosonsh and A, respectively. For a Higgs bosondecaying invisiblyand produced with the Standard Modelcross section, masses below 106.4 GeV/c^2 are excluded.
