Description :
A search with the DELPHI detector at LEP for excited leptons ($e^*$, $\mu^*$, $\tau^*$ and $\nu^*$) decaying through $\gamma$, W or Z transitions is reported. The data used correspond to an integrated luminosity of 10 pb$^{-1}$ at an $e^+e^-$ centre-of-mass energy of 161 GeV. The search for pair pro...

Description :
Using the data sample of hadronic $Z^0$ decays collected by the DELPHI experiment in the 1992-1995 LEP1 period, the leptonic decay of the charged $B$ mesons (\btauex) has been studied. The analysis was done in both leptonic \taulm and hadronic \tauxmm decay channels. No excess was observed in data a...

Description :
Inclusive distributions of charged particles in hadronic Wdecays are experimentally investigated using the statisticscollected by the DELPHI experiment at LEP during 1997, 1998and 1999, at centre-of-mass energies from 183 to around 200 GeV.The possible effects of interconnection betweenthe hadronic ...

Description :
Oscillations of $\mbox{B}^0_{\mathrm{s}}$ mesons have been studied in samples selected from about 3.5 million hadronic $\Zz$ decays detected by DELPHI betwee. One analysis uses events in the exclusive decay channels: $\Bs \rightarrow \rm{D}_{s}^{-} \pi^{+}$ or $\rm{D}_{s}^{-}\mathrm{a_1^+}$ and $\Bs...

Description :
Searches for spontaneous $R$-parity violating signals at $\sqrt{s}=183$\,GeV and \mbox{$\sqrt{s}=189$\,GeV} have been performed using 1997 and 1998 DELPHI data, under the assumption of $R$-parity breaking in the third lepton family. The expected topology for the decay of a pair of charginos into two...

Description :
Searches for pair production of gauginos and squarks in $e^{+} e^{-}$ collisions at a centre-of-mass energy of 189 GeV have been performed on data corresponding to an integrated luminosity of 158 pb$^{-1}$ collected by the DELPHI detector at LEP. The data were analyzed under the assumption of non-co...

Description :
Measurements of the trilinear gauge boson couplings $WW\gamma$ and $WWZ$ are presented using the data taken by DELPHI in 1998 at a centre-of-mass energy of 189~GeV and combined with DELPHI data at 183~GeV. Values are determined for \Dgz\ and \Dkg, the differences of the $WWZ$ charge coupling and of ...
