Study of final state photons in hadronicZ 0 decay and limits on new phenomena
The differential cross section for final state radiation from primary quarks is obtained from a study of isolated energetic photons produced in the reactione + e −→Z 0→hadrons+γ, as measured in the DELPHI detecto...

Search for excited charged leptons inZ 0 decays
Using a data sample of 115000 hadronicZ 0 decays, a search was performed for the production of excited charged leptons decaying into an ordinary lepton and one photon. Pair production of excited leptons of mass b...

Measurement of the partial width of theZ 0 intob \(\bar b\) final states using their semi-leptonic decays
The spectra of prompt electrons and muons from the semi-leptonic decays of heavy hadrons produced inZ 0 decays have been used to measure the coupling of theZ 0 tob quarks weighted by theB hadrons mean semi-lepton...

Search for low mass Higgs bosons produced inZ 0 decays
A search for light Higgs bosons was performed using the data sample collected in 1990 by the DELPHI detector at LEP, at centre of mass energies between 88.2 and 94.2 GeV. Using the process e+e−→H 0+Z 0*,Z 0*→ff, ...

A study of the EMC effect using neutrino and antineutrino interactions in neon and deuterium
Nearly 40000 neutrino and antineutrino interactions in BEBC are compared to measure the differences between neon and deuterium in the quark and antiquark distributions and in the nucleon structure functions. T...
