Production of $\Sigma^{0}$ and $\Omega^{-}$ in Z decays / DELPHI Collaboration
Reconstructed \lam\ baryon decays and photon conversions in DELPHI are used to measure the \sig\ production rate from hadronic Z^0 decays at LEP. The number of \sig\ decays per hadronic Z decay is found to be: \begin{center} < \sig + \sigb > = \wffe{0.070}{0.010}{0.010 }{}. [...]

Measurement of the charged particle multiplicity of weakly decaying B hadrons / DELPHI Collaboration
From the $Z$ decays recorded in 1994 and 1995 by the DELPHI detector at LEP, the charged particle multiplicity of weakly decaying $B$ hadrons was measured to be: \begin{center} $4.97 \pm 0.03 \pm 0.06 \, ,$ \end{center} \noindent excluding the $K^0$ and $\Lambda$ decay products..

Measurement of the triple gluon vertex from double quark tagged 4-jet events / DELPHI Collaboration
The 4-jet events collected by the DELPHI experiment at LEP1 in 1992, 1993 and 1994 are analysed to determine the contribution of the triple-gluon vertex. Two of the four jets are tagged as jets from $b$- or $c$-quarks using lifetime and lepton transverse momentum information [...]

Search for Lepton Flavour Number violating $Z^0$-Decays / DELPHI Collaboration
A search for lepton flavour number violating $Z^0$ decays in the channels \begin{center} $Z^0\rightarrow \mu\tau$,\\ $Z^0\rightarrow e\tau$, \\ $Z^0\rightarrow e\mu$, \\ \end{center} using the DELPHI detector with data collected during the 1991--94 LEP runs, is described. No signal was found. [...]

Determination of the average lifetime of b-baryons / DELPHI Collaboration
The average lifetime of b-baryons has been studied using 3 \times 10^6 hadronic Z^0 decays collected by the DELPHI detector at LEP. Three methods have been used, based on the measurement of different observables: the proper decay time distribution of 206 vertices reconstructed with a \Lambda, a lepton and an oppositely charged pion; the impact parameter distribution of 441 muons with high transverse momentum accompanied by a \mLs in the same jet; and the proper decay time distribution of 125 \Lambda_c-lepton decay vertices with the \Lambda_c exclusively reconstructed through its pK\pi, pK^0 and \mLs3\pi decay modes [...]

Measurement of the transverse spin correlation in $Z \to \tau^+\tau^-$ decays / DELPHI Collaboration
The measurement of the correlation between the transverse spin components of $\tau^+\tau^-$ pairs collected during 1992 to 1994 with the DELPHI detector at LEP1 is presented. A value \begin{center} $C_{TT}$~=~0.87~$\pm$~0.20~(stat.)~$^{+~0.10}_{-~0.12}$~(syst.) \end{center} was obtained for the correlation parameter, in agreement with the St1AU LYi,

First study of the interference between initial and final state radiation at the Z resonance / DELPHI Collaboration
The interference between initial and final state radiation in the process \eemm\ at $\sqs \approx \MZ$ has been studied by measuring the forward-backward asymmetry as a function of the acoplanarity angle between the final state muons. The interference is expected to be sensitive to the space-time separation of the initial and final state radiation. [...]

Measurement of $A_{FB}^{\overline{b}b}$ in Hadronic Z Decays using a Jet Charge Technique / DELPHI Collaboration
The $\BB$ forward-backward asymmetry %, $\AFBbb$, has been determined from the average charge flow %, $\langle Q_{FB}\rangle$, measured in a sample of 3,500,000 hadronic Z decays collected with the DELPHI detector in 1992 - 1995. The measurement is performed in an enriched $\BB$ sample selected using an impact parameter tag and results in the following values for the $\BB$ forward-backward asymmetry: \begin {center} \begin{tabular}{ccl} \AFBbb (89.55 GeV) & = & $0.068\,\ \pm0.018\,\ (\mbox{stat.})\pm0.0013 (\mbox{syst.})$ \\ \AFBbb (91.26 GeV) & = & $0.0982\pm0.0047(\mbox{stat.})\pm0.0016(\mbox{syst.})$ \\ \AFBbb (92.94 GeV) & = & $0.123\,\ \pm0.016\,\ (\mbox{stat.})\pm0.0027(\mbox{ syst.})$ \\ \end{tabular} \end{center} %at an average center of mass energy of 91.251\, GeV [...]

Measurement of the average lifetime of b-hadrons in Z decays / L3 Collaboration
We present a measurement of the average b-hadron lifetime ${\rm \tau_b}$ at the $\mathrm{e^+e^-} \, $ collider LEP. Using hadronic Z decays collected in the period from 1991 to 1994, two independent analyses have been performed [...]

Mean lifetime of the B$_{s}^{0}$ meson / DELPHI Collaboration
This paper presents an update of the measurement of the mean lifetime of the B^0_s meson. Combining D_s - \ell, D_s-h, \phi - \ell and inclusive D_s final states from the 3.2 million hadronic \Zz decays collected by DELPHI between 1991 and 1994, the B^0_s mean lifetime was measured to be: \tau(B^0_s) = 1.67 ~\pm 0.14, M014AU
