Data taken by DELPHI during the 1995 and 1996 LEP runs have been used to search for the supersymmetric partners of electron, muon and tau leptons and of top and bottom quarks. The observations are in...

An update of the searches for charginos and neutralinos is presented, basedon a data sample corresponding to the 53.9 pb$^{-1}$ recorded by the DELPHIdetector in 1997, at a centre-of-mass energy of...
Measurement of the mass of the W boson using direct reconstruction at $\sqrt{s}$ = 183 GeV (1999)

From data corresponding to an integrated luminosity of $53.5 \, {\mathrm {pb}}^{-1}$ taken during the $183 \, \GeV$ run in 1997, DELPHI has measured the W mass from direct reconstruction of $\WW...

Promptly decaying lightest charginos were searched for in the context of scenarios with gravitino LSP. It was assumed that the stau is the next to lightest supersymmetric particle (NLSP). Data...

The rate $Z \rightarrow b\overline{b}b\overline{b}$ was measured using about $2 x 10^6$ hadronic decays collected by the DELPHI experiment in 1994 and 1995. Events were forced into 3-jets with...
