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…

Measurement of Prompt Charm Meson Production Cross Sections in p anti-p Collisions at s**(1/2) = 1.96 TeV

The CDF Collaboration, D. Acosta

We report on measurements of differential cross sections d sigma/d p_t for prompt charm meson production in p anti-p collisions at s**(1/2) = 1.96 TeV using 5.8 +/- 0.3 pb-1 of dat…

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 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…
