A precise measurement of the direct CP violation parameter Re(epsilon'/epsilon)
NA48 Collaboration
The direct CP violation parameter Re(epsilon'/epsilon) has been measured from the decay rates of neutral kaons into two pions using the NA48 detector at the CERN SPS. With 3.3 mill…
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…
Hadronization properties of b quarks compared to light quarks in e+e- -> q qbar from 183 to 200 GeV
The DELPHI Collaboration, P. Abreu
The DELPHI detector at LEP has collected 54 pb^{-1} of data at a centre-of-mass energy around 183 GeV during 1997, 158 pb^{-1} around 189 GeV during 1998, and 187 pb^{-1} between 1…
Inclusive Sigma- and Lambda(1520) production in hadronic Z decays
The DELPHI Collaboration, P. Abreu
Production of Sigma- and Lambda(1520) in hadronic Z decays has been measured using the DELPHI detector at LEP. The Sigma- is directly reconstructed as a charged track in the DELPHI…
Space charge in ionization detectors and the NA48 calorimeter
Sandro Palestini
The effects of space charge due to slowly drifting ions can be relevant for detectors operated at high intensity, or for relatively low values of the bias voltage. Accurate measure…
A new measurement of direct CP violation in two pion decays of the neutral kaon
The NA48 Collaboration, V. Fanti
The NA48 experiment at CERN has performed a new measurement of direct CP violation, based on data taken in 1997 by simultaneously collecting K_L and K_S decays into pi0pi0 and pi+p…
Multiplicity Fluctuations in One- and Two-Dimensional Angular Intervals Compared with Analytic QCD Calculations
B. Buschbeck, F. Mandl
Multiplicity fluctuations in rings around the jet axis and in off-axis cones have been measured by the DELPHI collaboration in annihilations into hadrons at LEP energies.…
The Scale Dependence of the Hadron Multiplicity in Quark and Gluon Jets and a Precise Determination of
DELPHI Collaboration, P. Abreu et al
Data collected at the Z resonance using the DELPHI detector at LEP are used to determine the charged hadron multiplicity in gluon and quark jets as a function of a transverse momen…
