Charged and Identified Particles in the Hadronic Decay of W Bosons and in $e^{+}e^{-} \to q\overline{q}$ from 130 to 200 GeV / DELPHI Collaboration
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 decays of two Ws are not observed.Measurements of the average multiplicity for charged and identified particles in q$\bar{\mathrm q}$ and WW events at centre-of-mass energies from 130 to 200 GeV and in W decays are presented.The results on the average multiplicity of identified particlesand on the position $\xi^*$ of the maximum of the maximum of$\xi_p = -\mathrm{log} (\frac{2p}{\sqrt{s}})$distribution are compared with predictionsof JETSET and MLLA calculations..

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 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}. [...]

Observation of the Muon Inner Bremsstrahlung at LEP1 / DELPHI Collaboration
Muon bremsstrahlung photons converted in front of the DELPHI main tracker (TPC) in dimuon events at LEP1 were studied in two photon kinematic ranges: 0.2 < E_gamma <= 1 GeV and transverse momentum with respect to the parent muon p_T < 40 MeV/c, and 1 < E_gamma <= 10 GeV and p_T < 80 MeV/c . A good agreement of the observed photon rate with predictions from QED for the muon inner bremsstrahlung was found, contrary to the anomalous soft photon excess that has been observed recently in hadronic Z^0 decays.

Correlations between Polarisation States of W Particles in the Reaction $e^- e^+\to W^- W^+$ at LEP2 Energies 189-209 GeV / DELPHI Collaboration
In a study of the reaction e-e+ -> W-W+ with the DELPHI detector, the probabilities of the two W particles occurring in the joint polarisation states transverse-transverse (TT), longitudinal-transverse plus transverse-longitudinal (LT) and longitudinal-longitudinal (LL) have been determined using the final states WW -> l nu q qbar (l = e, mu). The two-particle joint polarisation probabilities, i.e. [...]

Search for one large extra dimension with the DELPHI detector at LEP / DELPHI Collaboration
Single photons detected by the DELPHI experiment at LEP2 in the years 1997-2000 are reanalysed to investigate the existence of a single extra dimension in a modified ADD scenario with slightly warped large extra dimensions. The data collected at centre-of-mass energies between 180 and 209 GeV for an integrated luminosity of ~650 pb^{-1} agree with the predictions of the Standard Model and allow a limit to be set on graviton emission in one large extra dimension.

Di-jet production in $\gamma\gamma$ collisions at LEP2 / DELPHI Collaboration
The production of two high-p_T jets in the interactions of quasi-real photons in e+e- collisions at sqrt{s_ee} from 189 GeV to 209 GeV is studied with data corresponding to an integrated e+e- luminosity of 550 pb^{-1}. The jets reconstructed by the k_T cluster algorithm are defined within the pseudo-rapidity range -1 < eta < 1 and with jet transverse momentum, p_T, above 3 GeV/c. [...]

Study of b-quark mass effects in multijet topologies with the DELPHI detector at LEP / DELPHI Collaboration
The effect of the heavy b-quark mass on the two, three and four-jet rates is studied using LEP data collected by the DELPHI experiment at the Z peak in 1994 and 1995. The rates of b-quark jets and light quark jets (l = uds) in events with n = 2, 3, and 4 jets, together with the ratio of two and four-jet rates of b-quarks with respect to light-quarks, R_n^bl, have been measured with a double-tag technique using the CAMBRIDGE jet-clustering algorithm.

Study of the Dependence of Direct Soft Photon Production on the Jet Characteristics in Hadronic $Z^0$ Decays / DELPHI Collaboration
An analysis of the direct soft photon production rate as a function of the parent jet characteristics is presented, based on hadronic events collected by the DELPHI experiment at LEP1. The dependences of the photon rates on the jet kinematic characteristics (momentum, mass, etc.) and on the jet charged, neutral and total hadron multiplicities are reported. [...]
