The performance of "Virtual Phase" CCDs as detectors of minimum-ionizing particles

The Texas Instruments "Virtual Phase" CCD has been the basis of an ambitious design for a precision vertex detector to be used at the Stanford Linear Collider. The performance of this chip shows promise for future use in electron linear colliders. Experimental results are reported in addition to description of the electronic readout and preliminary mechanical design.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/26549/1/0000088.pd

Charged particle multiplicity distributions in e + e − annihilation at 29 GeV: a comparison with hadronic data

The charged particle multiplicity distributions for two-jet events in e + e − annihilation at 29 GeV have been measured using the High Resolution Spectrometer at PEP. A Poisson distribution describes the data for both the complete event and for the single jets. In addition, no correlation is observed between the multiplicities in the two jets of an event. For fixed values of the prong number of the complete event, the multiplicity sharing between the two jets is in good agreement with a binomial distribution. The rapidity gap distribution is exponential with a slope equal to the mean rapidity density. These observations, which are consistent with a picture of independent emission of single particles, are contrasted to the results from soft hadronic collisions and conclusions are drawn about the nature of clusters.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/47881/1/10052_2005_Article_BF01570767.pd

Measurement of the inclusive KSO branching fraction in [tau] decay

The inclusive production of KSO mesons [tau] lepton decay has been studied using the high resolution spectrometer at the PEP e+e- storage ring operated at [radical sign]s=29 GeV. The data sample corresponds to an integrated luminosity of 300pb-1. The measured branching fraction is B([tau]--->KSOX-[nu][tau]) = (0.64+/-0.15)%. The measurement is consistent with all KSO coming from the Cabibbo-suppressed decay [tau]--->K*-(890)[nu][tau] with a branching ratio of (1.9+/-0.3+/-0.4)%.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/27329/1/0000352.pd
