Hbt Studies with E917 at the Ags: a Status Report
نویسندگان
چکیده
Two-particle correlations between pions in Au+Au collisions have been measured at beam kinetic energies of 6, 8, and 10.8 GeV/u at the Alternating Gradient Synchrotron (AGS) over a wide range of rapidities using a magnetic spectrometer. The data have been analyzed in the Hanbury-Brown and Twiss (HBT) framework to extract source parameters. The event-by-event orientation of the reaction plane has also been measured using a scintillator hodoscope at far forward rapidities, and beam vertexing detectors upstream of the target. A preliminary analysis of the dependence of the source parameters on the reaction plane is presented.

P56: A Case Report on a New Aicardi-Goutieres Syndrome Inducing Gene
Aicardi-Goutieres syndrome (AGS) is an inflammatory genetic disease inherited in an autosomal recessive manner. Common features of this disease are encephalopathy, splenomegaly and hepatomegaly, muscle stiffness, irritability, unstoppable crying, seizures and dilation in growth. According to previous studies, primary genes responsible for this Syndromes are as followed: TREX 1, RNASEH2A, RNASEH...
متن کاملPion freeze-out through HBT correlation in HICs from AGS/FAIR to RHIC energies
In this talk we present the results of two-pion HBT correlation at freeze-out in heavy ion collisions (HICs) from AGS to RHIC energies. The UrQMD hadron-string transport model as well as the CRAB analyzing program are adopted. Based on the cascade mode, in general, the calculations are satisfying and well in line with the experimental data although discrepancies are not negligible. Such as: I),...
متن کاملCentral and Non-central HBT from AGS to RHIC
We review the status of particle interferometry in ultra-relativistic nucleus-nucleus collisions. The theoretical focus is on the modelindependent space-time interpretation of HBT radius parameters and its extension to the geometrical and dynamical asymmetries generated in finite impact parameter collisions. On the experimental side, we give a complete account of all presently available data fo...
متن کاملBeam Energy Evolution of HBT Systematics at the AGS
We present preliminary results of the first π interferometry (HBT) excitation function at intermediate AGS energies. The beam energy evolution of the correlations' dependence on m T , centrality, and emission angle with respect to the reaction plane are discussed. Comparisons with predictions of the RQMD cascade model are made. Two-particle intensity interferometry (HBT) measurements have long ...
متن کاملAGS cell line xenograft tumor as a suitable gastric adenocarcinoma model: growth kinetic characterization and immunohistochemistry analysis
Objective(s): Gastric cancer is the third leading cause of cancer-related death worldwide. The overall survival rate of patients is poor because gastric cancers are usually diagnosed at the late stages. Therefore, further research is needed and appropriate research tools are required to develop novel therapeutic approaches.Materials and Methods: Eight female athymic nude mice with a C57BL/6 bac...
