- Abstract
- Results are presented of a search for pair production of heavy objects decaying into four hadronic jets, as expected for example from associated or pair production of MSSM Higgs bosons, hA ~or HH, using a data sample of 5.9pb−1 of e+e− collisions at s√=130−136GeV collected with the DELPHI detector at LEP in November 1995. The data and expectations from standard processes agree after four-jet selections. An analysis based on b-tagging finds no hA ~candidate with high mass. A study optimized to search for HH ~events with mass in the 40−50GeV/c2 range also finds no candidate. Finally a comparison is made with a recent ALEPH analysis which found an excess of four-jet events with high multiplicity and high mass. Such a signal is not observed in the DELPHI data, although a slight excess in the mass region around 105GeV/c2 is seen.
