Abstract:

The cross sections for the production of single charged and neutral intermediate vector bosons were measured using integrated luminosities of 52 pb-1 and 154 pb-1 collected by the experiment at centre-of-mass energies of 182.6 GeV and 188.6 GeV, respectively. The cross sections for the reactions were determined in limited kinematic regions. The results found are in agreement with the Standard Model predictions for these channels. © 2001 Elsevier Science B.V.

Abstract:

A new precise measurement of |Vcb| and of the branching ratio BR(B̄0 → D*+ℓ-v̄ℓ) has been performed using a sample of about 5000 semileptonic decays B̄0 → D*+ℓ-v̄ℓ, selected by the DELPHI detector at LEP I by tagging the soft pion from D*+ → D0π+. The results are: Vcb = (39.0 ± 1.5 (stat.)-2.6+2.5 (syst. exp.) ± 1.3 (syst. th.)) × 10-3, BR(B̄0 → D*+ℓ-v̄ℓ) = (4.70 ± 0.13 (stat.)-0.31+0.36 (syst. exp.))%. The analytic dependencies of the differential cross-section and of the Isgur-Wise form factor as functions of the variable w = vB0 · vD* have also been obtained by unfolding the experimental resolution. © 2001 Published by Elsevier Science B.V.

Abstract:

Higgs bosons predicted by the fermiophobic scenario within Two Higgs Doublets Models were searched for in the data collected by the DELPHI detector at centre-of-mass energies between 189 GeV and 202 GeV, corresponding to a total integrated luminosity of 380 pb-1. No signal was found and confidence limits were derived in the framework of possible extensions of the Standard Model Higgs sector. © 2001 Elsevier Science B.V.
