Charged-particle multiplicity in $e^+ e^- \rightarrow q \overline{q}$ events at 161 and 172 GeV and from the decay of the W boson / DELPHI Collaboration
The data collected by DELPHI in 1996 have been used to measure the average charged particle multiplicities and dispersions in $q\bar{q}$ events at centre-of-mass energies of $\sqrt{s}=161$~GeV and $\sqrt{s}=172$~GeV, and the average charge multiplicity in WW events at $\sqrt{s}=172$~GeV. The multiplicities in $q\bar{q}$ events are consistent with the evolution predicted by QCD. [...]

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 [...]

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..

Search for charginos, neutralinos and gravitinos at LEP / DELPHI Collaboration
An update of the searches for charginos and neutralinos in DELPHI is presented, based mainly on recent data collected at centre-of-mass energies of 161~GeV and 172~GeV. No signal is found. [...]

Search for neutral and charged Higgs bosons in $e^+ e^-$ collisions at $\sqrt{s}= 161 GeV$ and $172 GeV$ / DELPHI Collaboration
A search for neutral and charged Higgs bosons has been performed in the data collected by the {\sc DELPHI} detector at centre-of-mass energies of 161~GeV and 172~GeV. The analysis assumes either the pair-production of charged Higgs bosons, ${\mathrm H}^{\pm}$, or the production of the lightest neutral Higgs boson, h, with either a Z or a neutral pseudoscalar Higgs boson, A [...]

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..
