Small pad RPCs as detector for high granularity digital hadron calorimetry
Requirements for sampling hadron calorimetry with gaseous active medium and digital read-out for a future linear eþe -collider (FLC) are formulated. Monogap glass Resistive Plate Chamber (RPC) prototypes equipped with 1 cm read-out pads and operated in saturated avalanche and streamer modes are studied as a possible detector for digital hadron calorimetry. Operating characteristics of the proto...
متن کاملHadron production in two-photon collisions at LEP-L3∗
The reaction ee → eeγγ → ee hadrons is analysed for quasi-real virtual photons using data collected by the L3 detector during the LEP high energy runs at √ s = 183 and 189 GeV. Preliminary results on the cross sections σ(ee → ee hadrons) and σ(γγ → hadrons) are given in the interval 5 GeV ≤ Wγγ ≤ 145 GeV. The centre-of-mass energy dependence of the two-photon cross section is well described by ...
متن کاملHadron Energy Reconstruction for the ATLAS Calorimetry in the Framework of the Non-parametrical Method
This paper discusses hadron energy reconstruction for the ATLAS barrel prototype combined calorimeter (consisting of a lead-liquid argon electromagnetic part and an iron-scintillator hadronic part) in the framework of the non-parametrical method. The non-parametrical method utilizes only the known e/h ratios and the electron calibration constants and does not require the determination of any pa...
متن کاملHigh pT Direct Photon-Hadron Correlations Using the PHENIX Detector
Jet tomography, the study of differential energy loss of hard scattered partons to infer the density profile of the medium, is greatly improved by precise knowledge of the initial energy of the hard probe. As photons are not strongly interacting, the momentum of the recoil jet from a direct photon trigger is balanced, to a good approximation, by the momentum of the photon. The energy loss of th...
متن کاملStudy of ordered hadron chains with the ATLAS detector
The analysis of the momentum difference between charged hadrons in high-energy proton-proton collisions is performed in order to study coherent particle production. The observed correlation pattern agrees with a model of a helical QCD string fragmenting into a chain of ground-state hadrons. A threshold momentum difference in the production of adjacent pairs of charged hadrons is observed, in ag...
