Search for Scalar Top and Scalar Bottom Quarks in collisions at TeV
CDF Collaboration
We have searched for direct pair production of scalar top and scalar bottom quarks in 88 pb of collisions at TeV with the CDF detector. We looked f…
An investigation on the b quark mass
Fabrizio Palla
In this article I will review the measurements of the b quark mass performed by ALEPH and DELPHI and presented at the HEP99 Conference in Tampere. Very clean effects of the mass ru…

CDF Collaboration, T. Affolder
We have reconstructed the radiative decays and in collisions at TeV, and measured the fraction of $Υ(1S…
Search for Charmless Hadronic Decays of B Mesons with the SLD Detector
SLD Collaboration
Based on a sample of approximately 500,000 hadronic Z0 decays accumulated between 1993 and 1998, the SLD experiment has set limits on 24 fully charged two-body and quasi two-body e…
Search for a W' Boson via the Decay Mode W' -> mu nu in 1.8 TeV p-pbar Collisions
CDF Collaboration, F. Abe
We report the results of a search for a W' boson produced in p-pbar collisions at a center-of-mass energy of 1.8 TeV using a 107 pb-1 data sample recorded by the Collider Detector…
Measurement of the Helicity of W Bosons in Top Quark Decays
CDF Collaboration, T. Affolder
We use the transverse momentum spectrum of leptons in the decay chain t-->bW with W-->l nu to measure the helicity of the W bosons in the top quark rest frame. Our measurement uses…
Search for a Fourth-Generation Quark More Massive than the Z0 Boson in ppbar Collisions at sqrt(s) = 1.8 TeV
CDF Collaboration, T. Affolder
We present the results of a search for pair production of a fourth-generation charge -1/3 quark (b') in sqrt(s)=1.8 TeV ppbar collisions using 88 pb^(-1) of data obtained with the…
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…
Measurement of b Quark Fragmentation Fractions in p-pbar Collisions at sqrt(s)=1.8 TeV
T. Affolder, CDF Collaboration
We have studied the production of B hadrons in 1.8-TeV p-pbar collisions. We present measurements of the fragmentation fractions, f_u, f_d, f_s and f_baryon, of produced b quarks t…
