چکیده
We present a measurement of the electric charge of the top quark using pp collisions corresponding to an integrated luminosity of 2.7 fb(-1) at the CDF II detector. We reconstruct tt events in the lepton + jets final state. We use soft lepton taggers to determine the flavor of the b jets, which we use to reconstruct the top quark's electric charge and exclude an exotic top quark with -4/3 charge at 95% confidence level. This is the strongest exclusion of the exotic charge scenario and the first to use soft leptons for this purpose.

Study of Top-quark Production and Decay Vertices with LCD Fast Simulation
We report a study of top-quark reconstruction in ee → tt̄ events at a 500 GeV linear collider using the LCD Fast simulator. The initial study of top-quark anomalous couplings is also reported. The final states of 4 jets and lepton as well as 6 jets are used. Using the 4 jets and lepton final state, we estimate the preliminary sensitivities for form factors at the γ/Ztt̄ vertex. In the 6 jets reco...
متن کاملDirect Measurement of the Top Quark Charge at Hadron Colliders
We consider photon radiation in t̄t events at the upgraded Fermilab Tevatron and the CERN Large Hadron Collider (LHC) as a tool to measure the electric charge of the top quark. We analyze the contributions of t̄tγ production and radiative top quark decays to p p (−) → γ`±νb̄bjj, assuming that both b-quarks are tagged. With 20 fb−1 at the Tevatron, the possibility that the “top quark” discovered in...
متن کاملMeasurement of the Top Quark Mass in the Di-lepton Channel Using the Dalitz-Goldstein Method
This is a measurement of the mass of the top quark using a method developed by G. Goldstein and R.H. Dalitz. It is based on 2.0 fb−1 of data collected by the Collider Detector Facility at Fermi National Accelerator Laboratories. Di-lepton events were observed from colliding protons with anti-protons with √ s = 1.96 TeV in the Tevatron Collider. A total of 145 candidate events were observed with...
متن کاملMeasurement of the top quark cross - section in the single - lepton channel in pp collisions at √ s = 7 TeV using kinematic fits and b - tagging information with the ATLAS Experiment
The measurement of the t ¯ t production cross-section in the single-lepton channel in pp collisions at a centre-of-mass energy √ s =7 TeV is presented. The analysis is based on a multivariate discriminant distribution in 3, 4 and ≥ 5 jet bins using three kinematic variables and b-tagging information. With a data sample of about 35 pb −1 recorded by ATLAS in 2010 the inclusive top quark producti...
متن کاملLepton Asymmetry of the Universe and Charged Quark-Gluon Plasma
The lepton asymmetry of order one is not excluded experimentally and, if present, can lead to interesting phenomena in the early Universe. It is shown that, when the temperature is above the quark-hadron transition, the lepton asymmetry induces chemical potentials for electric charge and for baryon number, and makes the quarkgluon plasma electrically charged.
متن کاملHeavy Top Quark Searches in the Di-lepton Mode at the Tevatron
We present the results of a detailed study of the effects of b-tagging on the heavy top-quark signal and backgrounds for the modes of the di-lepton plus two high transverse energy jets at the Fermilab Tevatron. The general characteristics of the heavy top-quark signal events are also discussed so that a comparison can be made between b-tagging and imposing stringent kinematical cuts to eliminat...
