The NA52 experiment measured particle and antiparticle yields at 0° production angle over a wide range in rapidity lead-lead (Pb-Pb) collisions 158 A GeV/c with minimum bias trigger. Besides (106) antiprotons () (103) antideuterons total of five antihelium-3 were found. resulting invariant differential cross sections pt≃0 turn out to be E (d3σ)/(dp3) = (2.5 ± 1.8) × 10-7 bc3 GeV-2 y 3.4 the laboratory system (5.9 3.4) 10-8 4.0. results are discussed framework simple coalescence model.
The NA52 experiment searches for long-lived massive strange quark matter particles, so-called...
The results of the CMS tracker alignment analysis are presented using data from cosmic tracks, optical survey information, and laser system at Tracker Integration Facility CERN. During several months operation in spring summer 2007, about five million track events were collected with a partially active Tracker. This allowed us to perform first silicon modules tracks three different statistical approaches; validate performance; test stability structures under various stresses temperatures...
During summer 2006 a fraction of the CMS silicon strip tracker was operated in comprehensive slice test called Magnet Test and Cosmic Challenge (MTCC). At MTCC, cosmic rays detected muon chambers were used to trigger readout all sub-detectors general data acquisition system presence 4 T magnetic field produced by superconducting solenoid. This document describes operation Tracker hardware software prior, during after taking. The performance detector as resulting from MTCC analysis is also presented.
In March 2007 the assembly of Silicon Strip Tracker was completed at Integration Facility CERN. Nearly 15% detector instrumented using cables, fiber optics, power supplies, and electronics intended for operation LHC. A local chiller used to circulate coolant low temperature operation. order understand efficiency alignment strip tracker modules, a cosmic ray trigger implemented. From through July 4.5 million triggers were recorded. This period, referred as Sector Test, provided practical...
We investigate the production mechanisms of p, d, t, 3He, 4He, 6Li, , and in Pb+Pb collisions at 158 A GeV measured near zero transverse momentum with NA52 experiment CERN SPS. find evidence that nuclei antinuclei are mainly produced via coalescence mechanism out a thermalized source hadrons, time close to thermal freeze-out hadrons corresponding temperature ~120 MeV.
