Measurement of theBs0→μ+μ−Branching Fraction and Search forB0→μ+μ−with the CMS Experiment

TeV with the CMS experiment

A measurement of the J/ψ and ψ(2S) production cross sections in pp collisions at √ s = 7 TeV with the CMS experiment at the LHC is presented. The data sample corresponds to an integrated luminosity of 37 pb −1. Using a fit to the invariant mass and decay length distributions, production cross sections have been measured separately for prompt and non-prompt charmonium states, as a function of th...

Jets in CMS Experiment

The CMS experiment at the CERN LHC

The Compact Muon Solenoid (CMS) detector is described. The detector operates at the Large Hadron Collider (LHC) at CERN. It was conceived to study proton-proton (and leadlead) collisions at a centre-of-mass energy of 14 TeV (5.5 TeV nucleon-nucleon) and at luminosities up to 1034 cm−2s−1 (1027 cm−2s−1). At the core of the CMS detector sits a high-magneticfield and large-bore superconducting sol...

The Rpc System for the Cms Experiment at Lhc 1 Cms Detector 2 Cms Muon Trigger

The CMS experiment designed for Large Hadron Collider is brieey described. An idea of a muon trigger based on RPC is presented. This talk focuses on the requirements on RPC as the trigger detectors for the CMS. We discuss the required chamber's parformance and segmentation. Current design of the system fulllling these requirements is presented. Its expected trigger performances are given. The a...

the search for the self in becketts theatre: waiting for godot and endgame

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
