Measurement of the top quark mass at CMS
The top quark mass is an important parameter of the standard model (SM) and it affects predictions of SM observables via radiative corrections. A precise measurement of the top quark mass is crucial since it constitutes one of the most important inputs to the global electroweak fits [1], which provide constraints on the model itself, including indirect limits on the mass of the Higgs boson. The...
متن کاملSearch for supersymmetry in top final states at CMS
A search for SUSY using the top quark plus missing transverse energy (MET), in a low mass mSUGRA test point is performed. A two–constraints kinematic fit is utilized to extract the top quark, either b-jet the ones that is recognizable or it is not recognizable. It is shown that for point LM1, for the former situation, a 5σ excess can be achieved with 30 pb-1 and for the latter situation, it can...
متن کاملTop Mass Measurement at Cdf
We report on recent measurements of the top quark mass using tt̄ candidate events selected in ≃ 320 pb of data from the ”Run II” operation period of the Tevatron pp̄ collider. More emphasis is given on the best single measurement to date (Mtop = 173.5 +3.9 −3.8 GeV/c ), provided by CDF using the ”lepton plus jets” channel, where one W decays to a lepton-neutrino pair and the other into quarks (to...
متن کاملPrecision top-quark mass measurement at CDF.
We present a precision measurement of the top-quark mass using the full sample of Tevatron √s = 1.96 TeV proton-antiproton collisions collected by the CDF II detector, corresponding to an integrated luminosity of 8.7 fb(-1). Using a sample of tt¯ candidate events decaying into the lepton+jets channel, we obtain distributions of the top-quark masses and the invariant mass of two jets from the W ...
متن کاملTop Physics at ATLAS and CMS
The potential for top quark physics of the ATLAS and CMS experiments at the Large Hadron Collider is surveyed ranging from top quark " re-discovery " and its use as a calibration tool to initial and later stage measurements.
