Measurement of the Quark and Gluon Fragmentation Functions in $Z^0$ Hadronic Decays / DELPHI Collaboration
The fragmentation functions and multiplicities in $b\overline{b}$ and light quark events are compared. The measured transverse and longitudinal components of the fragmentation function allow the gluon fragmentation function to be evaluated..

Identified particles in quark and gluon jets / DELPHI Collaboration
A sample of about 1.4 million hadronic \z decays, selected among the data recorded by the DELPHI detector at LEP during 1994, was used to measure for the first time the momentum spectra of \kp, \ko, \p, \l and their antiparticles in gluon and quark jets. As observed for inclusive charged particles, the production spectra of identified particles were found to be softer in gluon jets than in quark jets, with a higher total multiplicity..

Search for Neutral Heavy Leptons Produced in Z Decays / DELPHI Collaboration
Weak isosinglet Neutral Heavy Leptons ($\nu_m$) have been searched for using data collected by the DELPHI detector corresponding to $3.3\times 10^{6}$ hadronic~Z$^{0}$ decays at LEP1. Four separate searches have been performed, for short-lived $\nu_m$ production giving monojet or acollinear jet topologies, and for long-lived $\nu_m$ giving detectable secondary vertices or calorimeter clusters. [...]

A Measurement of $\alpha_s$ from the Scaling Violation in $e^+ e^-$ Annihilation / DELPHI Collaboration
The hadronic fragmentation functions of the various quark flavours and of gluons are measured in a study of the inclusive hadron production from $\zz$ decays with the DELPHI detector and are compared with the fragmentation functions measured elsewhere at energies between 14 GeV and 91 GeV. A large scaling violation is observed, which is used to extract the strong coupling constant from a fit using a numerical integration of the second order DGLAP evolution equations. [...]

A precise measurement of the $B^{0}_{d}$ meson lifetime using a new technique / DELPHI Collaboration
From data recorded by DELPHI between 1991 and 1994, which correspond to 3.2 million hadronic $\mbox{Z}^0$ decays, a measurement of the $\Bdb$ meson lifetime has been performed based on the inclusive reconstruction of $3520 \pm 150$ semileptonic decays of the type \bc $\Bdb \rightarrow \Dstarp ~X~\ell^-~ \overline{\nu_{\ell}}, $ \ec The result is: \bc $\tau(\Bdb) = 1.537~\pm 0.041 (stat.) \pm 0.039 (syst.) ~\mathrm{ps}$. \ec \noindent The contribution to the systematic uncertainty which depends on external errors is $\pm 0.014~\mathrm{ps}$..

An Upper Limit for $Br(Z^0 \rightarrow ggg)$ from Symmetric 3-jet $Z^0$ Hadronic Decays / DELPHI Collaboration
An upper limit for $BR(Z^0\ rightarrow 3g)$ is obtained from a correlation method, which distinguishes statistically between quark and gluon jets by using the difference in their charged particle multiplicity distributions. From the sam020AU LW

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. [...]

Tuning and Test of Fragmentation Models Based on Identified Particles and Precision Event Shape Data / DELPHI Collaboration
Event shape and charged particle inclusive distributions are measured using 750000 decays of the $Z$ to hadrons from the DELPHI detector at LEP. These precise data allow a decisive confrontation with models of the hadronization process. [...]

Search for Pair Production of Heavy Objects in 4-Jet Events at $\sqrt{s}=130-136$ GeV / DELPHI Collaboration
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 $5.9\;$pb$^{-1}$ of $e^+ e^-$ collisions at $\sqrt{s}=130-136\;{\mathrm {GeV}}$ collected with the DELPHI detector at LEP in November 1995. The data and expectations from standard processes agree after four-jet selections. [...]
