Abstract (data abstract)
CERN-LHC. Search for long-lived massive paricles in proton-proton collision at a centre-of-mass energy of 7 TeV using a data sample of total integrated luminsoity of 34 pb-1. The slow-moving charged particles are identified using two techniques, the rate of energy loss in the Pixel detector and the time of flight in the Tile Calorimeter. Data are presented on both of these measured quantities together with mass estimates of the heavy partice (R-Hadron) after suitable cuts designed to maximize the R-hadrons signal from gluino and squark pair production. Theoretical estimates expected from the Standard Model background and also signals from SUSY models with differening gluino masses are also tabulated. The paper give upper bounds to the observed cross sections.
