An alternative Invisible Higgs search performed with ALPHA++

An invisibly decaying Higgs boson has been searched for in ALEPH using 798.9pb-1 data from 1998 to 2000. This search has been carried out using the ALEPH++ software. The obtained limits are in good agreement with the published final ALEPH results. Assuming a standard model cross section and a 100% b...

Sumario:An invisibly decaying Higgs boson has been searched for in ALEPH using 798.9pb-1 data from 1998 to 2000. This search has been carried out using the ALEPH++ software. The obtained limits are in good agreement with the published final ALEPH results. Assuming a standard model cross section and a 100% branching ratio, the obtained limit is 111.8GeV/c2 whereas the expected limit at 95% confidence level was 112.64GeV/c2.
