Top physics at CMS/LHC
No full textRecent results on the inclusive and differential production cross sections of top-quark pair and single top-quark processes are presented, obtained using data from proton-proton collisions collected with the CMS detector at the LHC. The large centre-of-mass energies available at LHC allow for the copious production of top-quark pairs in association with other final state particles at high transverse momentum. Measurements of such processes as well as of the top-quark mass and other properties will be discussed. The results are compared with the most up-to-date standard model theory predictions
CMS ECAL Calibration Strategy
No full textThe CMS Electromagnetic crystal Calorimeter (ECAL) must be precisely calibrated if its full potential performance is to be realized. Inter-calibration from laboratory measurements and cosmic rays will be available for all crystals and has been demonstrated to be good pre-calibration values at the start-up; some crystals will be also inter-calibrated using an electron beam. In-situ calibration with physics events will be the main tool to reduce the constant term of the energy resolution to the design goal of 0.5%. In the following the calibration strategy will be described in detail

Search for the MSSM decay with
No full textThe CMS potential for a simultaneous search for the CP-odd pseudo-scalar Higgs boson (A) and the CP-even scalar Higgs boson (h) is presented in the decay channel A->Zh with Z->ll (l=e,mu) and h->b bbar. The statistical signal significance and the systematic uncertainties are discussed

No full textInclusive W and Z production at LHC startup
No full textWe report on the potential measurement of the inclusive W and Z boson production cross section with the CMS detector at the LHC assuming pp collision data at a center-of-mass energy of 14 TeV. We have designed W and Z triggers, selection algorithms and event reconstruction techniques for both muon and electron decay modes, for low luminosity operation of the LHC integrating up to about 10 /pb. Initial calibrations and alignment conditions are assumed. While the accuracy of the cross section extracted will be dominated by the integral luminosity measurement, the understanding of the rate and characteristics of these processes will be of vital importance for the LHC physics programme
Inclusive W/Z cross section and W charge asymmetry measurements at the LHC
No full textMeasurements of inclusive W and Z production cross sections and their luminosity-independent
ratios as well as the lepton charge asymmetry in the inclusive W production are presented, for both electron and muon decay channels. The measurements are based on data recorded in proton-proton collisions at a centre-of-mass energy of 7 TeV by the ATLAS and CMS experiments at the LHC. The results are compared with the theoretical predictions and it is expected to provide additional constraints on the parton distribution functions of the proton
