“Measurement of tau hadronic decays branching ratios

including kaon identification at DELPHI”

Dmitri Dedovich

Abstract:

Exclusive and semi-exclusive branching ratios of the tau lepton

hadronic decay modes with up to six hadrons measured with data

from the DELPHI detector at LEP.

We also present preliminary results on the inclusive production of

charged kaons in one-prong tau decays. Branching ratio of tau->K X

nu has been obtained using combined information from DELPHI RICH

detector and from ionisation loss measurement.
