No full textCollective characteristics are studied of hadrons produced in beam fragmentation of non-single-diffractive ß + p-interactions at 250 GeV/c. An attempt is made to obtain experimental information on the properties of leading cluster production and fragmentation. On average, the leading cluster carries 0.8\Sigma0.1 of the incident momentum, so that the mean value of the inelasticity coefficient of hki=0.2\Sigma0.1 is significantly smaller than that deduced from leading single hadron spectra. The momentum transfer distribution shows that non-single-diffractive processes are less peripheral than diffraction dissociation. The analysis of thrust and sphericity shows jet-like structure of pion fragmentation, that of the charge flow an average forward charge of hQ f i = 0:45 \Sigma 0:04 in agreement with the average charge of the beam valence quarks. Our data are compared to diffraction dissociation and to the Fritiof model. 1. Introduction According to a number of models of high energy ha..

The hadron calorimeter prototype beam-test results
No full textHere We present here the beam-test results obtained with the HCAL Prototype exposed on the X7 beam line of the CERN SPS accelerator. The iron plate: - scintillator tile sampling calorimeter has been tested in the bearn momenta range 10 = 80 GeV/c. The measured energy, angular and coordinate dependences of the HCAL responce and resolution were found to be corresponding to the LHCb design requirements. The angular and X-Y coordinate uniformity have been checked and compared with stand-alone Monte-Carlo simulation program predictions. The radioactive source calibration procedure has been developed. The LED pulse system allows to monitor the short-term stability of the detector. New 40 MHz front-end electronics have been tested and compared with ordinary charge integrating ADC's. The results of the first combined calorimeter tests are also presented. The signal shapes have been studied for FICA L., instrumented with different fiber types and were found to satisfy the I,IICb performance requirements

No full text: A collective "sea-gull" effect is observed for a system of fast hadrons produced in the fragmentation regions of non-diffractive ß + p-interactions at 250 GeV/c. The effect is not reproduced by the FRITIOF fragmentation model in its details. It is demonstrated that hard-like processes, both in the collision phase and in the fragmentation phase, are not properly treated in the model. a Now at Univ. Instelling Antwerpen b EC guest scientist c Onderzoeksleider NFWO, Belgium d Partially supported by grants fromCPBP 01.06 and 01.09 As observed recently [1], scaling violation in the dependence of the average transverse momentum hp T i on Feynman x F (lifting of the so-called "sea-gull" wings with increasing energy p s) does not only occur in hard collisions such as e + e \Gamma annihilation [2] or lepton-nucleon scattering [3-5], but also in "soft" hadron-hadron collisions. In hard collisions, the non-scaling effects are attributed to hard gluon emission by one or two lead..
