Search for single top production via FCNC at LEP at sqrt(s) = 189-208 GeV
The DELPHI Collaboration, J. Abdallah
A search for single top production (e+e- -> t cbar) via Flavour Changing Neutral Currents (FCNC) was performed using the data taken by the DELPHI detector at LEP2. The data analyse…
Determination of |Vub|/|Vcb| with DELPHI at LEP
The DELPHI Collaboration, P. Abreu
The ratio of the CKM quark-mixing matrix elements |Vub|/|Vcb| has been measured using B hadron semileptonic decays. The analysis uses the reconstructed mass M_X of the secondary ha…
Rapidity-Rank Structure of p pbar Pairs in Hadronic Z0 Decays
The DELPHI Collaboration, P. Abreu
The rapidity-rank structure of p pbar pairs is used to analyze the mechanism of baryon production in hadronic Z0 decay. The relative occurrence of the rapidity-ordered configuratio…
Measurement of V_{cb} from the decay process \bar{B^0} -> D^{*+} \ell^- \barν
The DELPHI Collaboration, P. Abreu
A new precise measurement of |V_{cb}| and of the branching ratio BR(\bar{B^0} -> D^{*+} \ell^- \bar{ν_\ell}) has been performed using a sample of about 5000 semileptonic decays \ba…
Search for charginos in e+e- interactions at sqrt(s) = 189 GeV
The DELPHI Collaboration, P. Abreu
An update of the searches for charginos and gravitinos is presented, based on a data sample corresponding to the 158 pb^{-1} recorded by the DELPHI detector in 1998, at a centre-of…
Search for Heavy Stable and Long-Lived Particles in e+e- Collisions at sqrt(s)=189 GeV
The DELPHI Collaboration, P. Abreu
A search for stable and long-lived heavy charged particles was performed using the data taken by the DELPHI experiment at an energy of 189 GeV. The Cherenkov light detected in the…
