EUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH One and two dimensional analysis of 3π correlations measured in Pb+Pb interactions

چکیده
π − π − π − correlations from Pb+Pb collisions at 158 GeV/c per nucleon are presented as measured by the focusing spectrometer of the NA44 experiment at CERN. The three-body effect is found to be stronger for PbPb than for SPb. The twodimensional three-particle correlation function is also measured and the longitudinal extension of the source is larger than the transverse extension.

European pond turtle (Emys orbicularis persica) as a biomarker of environmental pollution in Golestan and Mazandaran provinces, Iran
Anthropogenic environmental changes are hypothesized as main reasons for animal species population declines. Heavy metals contamination is one of the worst threats to animals among human-caused threats. As most of the heavy metals bioaccumulate in organisms, analyzing concentrations of heavy metals in long living animals, such as turtles, would be very useful for biomonitoring of environmental ...
متن کاملOptimization of a SPECT system for imaging of 90Y in liver using Monte Carlo method
Introduction: Acquiring a high quality image has assigned an important concern for obtaining accurate diagnosis in nuclear medicine. Detector and collimator are critical component of Single Photon Emission Computed Tomography (SPECT) imaging system for giving accurate information from exact pattern of radionuclide distribution in the target organ. The images are strongly affect...
متن کاملModeling Magnetic Field in Heavy ion Collisions Using Two Different Nuclear Charge Density Distributions
By studying the properties of matter during heavy-ion collisions, a better understanding of the Quark-Gluon plasma is possible. One of the main areas of this study is the calculation of the magnetic field, particularly how the values of conductivity affects this field and how the field strength changes with proper time. In matching the theoretical calculations with results obtained in lab, two diffe...

The present work has been carried out to investigate the removal efficiency of active oxygen, produced by using APGP cold plasma sterilizer, on the heavy metals of Hg, Pb and Total Suspended Solids in discharge wastewater of Shif shrimp culture complex and Persian Gulf SPF shrimp research center in Bushehr province. The maximum of removal efficiency for Hg and Pb were 66% and 74%, respectively...
متن کاملProduction and Angular Correlations in 158 A GeV p + A and
Recent results of the WA98 experiment with p and Pb induced reactions at 158 AGeV are presented. Azimuthal γ-γ correlations at high p T were studied in search for a signal of jet-like structures. A clear indication for back-to-back correlations can be seen in p+A with a strong dependence on the p T of the photons and the size of the system. In Pb+Pb collisions in plane elliptic flow has been ob...
