Top results from CMS
The top quark has a special place in the Standard Model (SM). It is the heaviest elementary particle known to date, its mass [1] being very close to the scale of electroweak symmetry breaking. As such it plays a special role in many models of new physics beyond the SM. In the SM, the top quark decays almost exclusively to a W b pair. At the LHC [2], the top quark is predominantly produced in pa...
متن کاملSoft QCD Results from CMS
Studies of hadron production in proton-proton collisions, including charged particle transverse momentum, pseudo-rapidity and event-by-event multiplicity distributions at √ s = 0.9, 2.36 and 7 TeV are shown. Measured spectra of identified strange hadrons, reconstructed based on their decay topology, are also presented. Comparisons to several QCD Monte Carlo models and tunes are discussed. Resul...
متن کاملIntroduction to CMS from a CS viewpoint
Most of this text follows the ‘main stream’ of CMS very closely. However I have not always marked places where the document goes beyond ‘main stream’ CMS thinking. The thesis deals with the development of an efficient, self-optimising storage layer for event data. The layer is intended to manage storage space located in a single computer centre, so wide-area issues are not discussed in depth be...
متن کاملCMS NOTE 1997 / 003 CMS Note
Abstract A 2 mm gas gap Resistive Plate Chamber with bakelite plates has been operated in avalanche mode under a 137Cs source irradiation. We report on measurements of the efficiency in cosmic rays detection and of the charge developed in the gap, performed for two different gas mixtures: the first containing a high percentage of environmental friendly ”freon” C2H2F4; the second one having a hi...
متن کاملon CMS information server CMS NOTE 1997 / 004 CMS Note The Compact Muon Solenoid Experiment
Some properties of a 90% C2H2F4 gas mixture, used to operate resistive plate chambers in avalanche mode, are determined by comparing the experimental results with the prediction of simple analytical calculations. The fast charge distribution of the signal induced on pick-up electrodes is reproduced by means of a Monte Carlo simulation of the avalanche development. In addition predictions for a ...
