ATLAS beam test results

Many different configurations of electronics and semiconductor strip detectors were studied in 1995 using the ATLAS tracking detector test area at the H8 beam-line of the CERN SPS. A significant fraction of these investigations are presented elsewhere in this volume and this paper will concentrate on the results with silicon strip detectors read out with electronics preserving the pulse height information. Data has been collected with the ADAM, APV5 and FElix read-out chips on a number of different detectors. The first results are presented for read out with LHC electronics of detectors to the ATLAS-A specification of 112.5 μm pitch, employing n-strips in n-type silicon, capacitive coupling and intermediate strips. It is demonstrated that with adequate signal/noise, a spatial resolution of ≃13 μm is attainable with these detectors

Field of study

The time dependent mixing of B-d(0)-(B) over bar(d)(0) mesons has been observed by using the correlations between the charge of D-* mesons and the weighted mean charge of particles in each hemisphere. From a reconstructed D-*+/- sample corresponding to about 1.7 million hadronic Z(0) decays, the mass difference between the two B-d(0) mass eigenstates has been measured to be hm = 0.50 +/- 0.12 (stat.) +/- 0.06 (syst.) (h) over bar/ps or, converting into eV/c(2): Delta m = [3.29 +/- 0.79 (stat.) +/- 0.39 (syst.)] 10(-4) eV/c(2)
