Measurement of the Tau Lepton Polarisation at LEP2 / DELPHI Collaboration
A first measurement of the average polarisation P_tau of tau leptons produced in e+e- annihilation at energies significantly above the Z resonance is presented. The polarisation is determined from the kinematic spectra of tau hadronic decays. [...]

A Study of $b\overline{b}$ Production in $e^{+}e^{-}$ Collisions at $\sqrt{s}$ = 130-207 GeV / DELPHI Collaboration
Measurements are presented of R_b, the ratio of the b bbar cross-section to the q qbar cross-section in e+e- collisions, and the forward-backward asymmetry A^b_FB at twelve energy points in the range sqrt(s) = 130-207 GeV. These results are found to be consistent with the Standard Model expectations. [...]

Search for neutral MSSM Higgs bosons at LEP / ALEPH Collaboration
The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for the neutral Higgs bosons which are predicted by the Minimal Supersymmetric Standard Model (MSSM). The data of the four collaborations are statistically combined and examined for their consistency with the background hypothesis and with a possible Higgs boson signal. [...]

Measurement of the Mass and Width of the W Boson in $e^{+}e^{-}$ Collisions at $\sqrt{s}$ = 161 - 209 GeV / DELPHI Collaboration
A measurement of the W boson mass and width has been performed by the DELPHI collaboration using the data collected during the full LEP2 programme (1996-2000). The data sample has an integrated luminosity of 660 pb^-1 and was collected over a range of centre-of-mass energies from 161 to 209 GeV. [...]

Study of W boson polarisations and Triple Gauge boson Couplings in the reaction $e^{+}e^{-} \to W^{+}W^{-}$ at LEP 2 / DELPHI Collaboration
A determination of the single W Spin Density Matrix (SDM) elements in the reaction e+e- -> W+W- -> l nu q qbar (l=e/mu) is reported at centre-of-mass energies between 189 and 209 GeV. The data sample used corresponds to an integrated luminosity of 520 pb^{-1} taken by DELPHI between 1998 and 2000. [...]

Higgs boson searches in CP-conserving and CP-violating MSSM scenarios with the DELPHI detector / DELPHI Collaboration
This paper presents the final interpretation of the results from DELPHI on the searches for Higgs bosons in the Minimal Supersymmetric extension of the Standard Model (MSSM). A few representative scenarios are considered, that include CP conservation and explicit CP violation in the Higgs sector. [...]

Search for $B^{0}_{s}-\overline{B^{0}_{s}}$ oscillations in DELPHI using high-$p_{t}$ leptons / DELPHI Collaboration
Oscillations in the $\mbox{B}^0_s$-$\overline{\mbox{B}^0_s}$ system were studied in events selected from about 4.3 million hadronic Z$^0$ decays registered by DELPHI between 1992 and 2000.\\ This paper presents updates of two published analyses. The first analysis, which utilizes leptons emitted with large momentum transverse to a jet, was improved by means of a better algorithm for the vertex reconstuction and a new algorithm for flavour-tagging at production time [...]

Search for a fourth generation b'-quark at LEP-II at sqrt{s}=196-209 GeV / DELPHI Collaboration
A search for the pair production of fourth generation b'-quarks was performed using data taken by the DELPHI detector at LEP-II. The analysed data were collected at centre-of-mass energies ranging from 196 to 209 GeV, corresponding to an integrated luminosity of 420 pb^{-1}. [...]

A study of the b-quark fragmentation function with the DELPHI detector at LEP I and an averaged distribution obtained at the Z Pole / DELPHI Collaboration
The nature of b-quark jet hadronisation has been investigated using data taken at the Z peak by the DELPHI detector at LEP. Two complementary methods are used to reconstruct the energy of weakly decaying b-hadrons, E^weak_B. [...]
