A study of the b-quark fragmentation function with the DELPHI detector at LEP I and an averaged distribution obtained at the Z Pole

J. Abdallah, P. Abreu, W. Adam, P. Adzic et autres

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, $E_{\mathrm{B}}^{\mathrm{weak}}$ . The average value of $x^{\mathrm{weak}}_{\mathrm{B}} …

Search for single top quark production via contact interactions at LEP2

J. Abdallah, P. Abreu, W. Adam, P. Adzic et autres

Single top quark production via four-fermion contact interactions associated to flavour-changing neutral currents was searched for in data taken by the DELPHI detector at LEP2. The data were accumulated at centre-of-mass energies ranging from 189 to 209 GeV, with an integrated luminosity …

Study of the dependence of direct soft photon production on the jet characteristics in hadronic Z 0 decays

J. Abdallah, P. Abreu, W. Adam, P. Adzic et autres

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, …

Measurements of CP-conserving trilinear gauge boson couplings WWV (V≡γ,Z) in e+e− collisions at LEP2

J. Abdallah, P. Abreu, W. Adam, P. Adzic et autres

The data taken by Delphi at centre-of-mass energies between 189 and 209 GeV are used to place limits on the CP-conserving trilinear gauge boson couplings $\Delta g^{Z}_{1}$ , λ γ and Δκ γ associated to W + W − and single W …

Correlations between polarisation states of W particles in the reaction e − e +→W − W + at LEP2 energies 189–209 GeV

J. Abdallah, P. Abreu, W. Adam, P. Adzic et autres

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 …

Inclusive single-particle production in two-photon collisions at LEP II with the DELPHI detector

J. Abdallah, P. Abreu, W. Adam, P. Adzic et autres

A study of the inclusive charged hadron production in two-photon collisions is described. The data were collected with the DELPHI detector at LEP II. Results on the inclusive single-particle pT distribution and the differential charged hadrons dσ/dpT cross-section are presented and compared …

J. Abdallah, P. Abreu, W. Adam, P. Adzic et autres

Measurements are presented of R b, the ratio of the ${\mathrm{b}}\bar{\mathrm{b}}$ cross-section to the ${\mathrm{q}}\bar{\mathrm{q}}$ cross-section in e+e− collisions, and the forward-backward asymmetry A FB b at twelve energy points in the range $\sqrt{s}=130$ –207 GeV. These results are found to be …

Search for one large extra dimension with the DELPHI detector at LEP

J. Abdallah, P. Abreu, W. Adam, P. Adzic et autres

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 …

Observation of the muon inner bremsstrahlung at LEP1

J. Abdallah, P. Abreu, W. Adam, P. Adzic et autres

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 γ ≤1 GeV and transverse momentum with respect to the parent muon p T <40 MeV/c, and …
