Silicon strip detectors with capacitive charge division

Abstract Measurements of the behaviour of various high-resolution silicon strip detectors with capacitive charge division have been made in a high-energy particle beam. The results are compared with an electrostatic model which calculates the charges deposited on the strips after the passage of a minimum ionizing particle. Good agreement is found and the model is used to propose a method of improving the charge-division properties of such detectors.

Production ofD, D* andD s mesons in 200 GeV/c π−K− andp-Si interactions

The NA 32 experiment at the CERN SPS has collected 38 million hadronic interactions with incident 200 GeV/c π−,K− andp beam. Using a segmented silicon active target and a telescope of high resolution silicon microstrip counters we have selected fully reconstructedD0→K−π+,D0→K−π+π+π−,D+→K−π+π+,Ds+→K−K+π+π+ and charge conjugate decays. The integrated cross-sections forDo,D+D*+ andDs+ meson production and the dependence of the cross-section on longitudinal and transverse momentum of theD are presented.

Measurement of the lifetime of charged and neutralD mesons with high resolution silicon strip detectors

AbstractWe have measured the lifetime of charged and neutralD mesons using high resolution silicon strip detectors in the NA11 spectrometer at the CERN SPS. TheD mesons were produced in 200 GeV π− interactions. We obtain a value of
