چکیده
We present a direct measurement of the mass difference between t and t quarks using tt candidate events in the lepton+jets channel, collected with the CDF II detector at Fermilab's 1.96 TeV Tevatron pp Collider. We make an event by event estimate of the mass difference to construct templates for top quark pair signal events and background events. The resulting mass difference distribution of data is compared to templates of signals and background using a maximum likelihood fit. From a sample corresponding to an integrated luminosity of 5.6 fb(-1), we measure a mass difference, ΔM(top) = M(t) - M(t) = -3.3 ± 1.4(stat) ± 1.0(syst) GeV/c2, approximately 2 standard deviations away from the CPT hypothesis of zero mass difference.

Precise measurements of the top mass and direct measurement of the mass difference between top and antitop quarks at DØ
We report on measurements of the mass using dilepton and lepton+jet data collected with the D0 detector. These results are compared to the top mass extracted from the t ¯ t cross section using higher-order quantum chromodynamics calculations. We also present a direct measurement of the mass difference between top and antitop quarks (∆m) in lepton+jets t ¯ t final states using the " matrix eleme...
متن کاملDual-energy X-ray absorptiometry diagnostic discordance between Z-scores and T-scores in a young Iranian population
Background: Dual-energy X-ray Absorptiometry (DXA) is considered the gold standard for non-invasive measurement of bone mass. T-scores and Z-scores are used to present the results of bone mass. The present study was designed to evaluate the discordance between T-scores and Z-scores calculated at a same level and its relation with age, gender and body mass index (BMI) in a representative sampl...

متن کاملComparison of Total Fat, Percentage of Fat, Trunk Fat, Soft Lean and Mass Waist-Hip Ratio between Diabetic type II and Matched Non-Diabetic Iranians using Bioelectrical Impedance Analysis
Introduction: Research shows a relationship between diabetes (type II) and obesity. Bioelectrical Impedance Analysis (BIA) is a relatively new and approved method for the measurement of body composition. The aim of this study was to compare diabetic and non-diabetic adults on the basis of waist-hip ratio, total fat, percentage of fat, trunk fat, and soft lean mass. Methods: In this cross-sec...

متن کاملMixing of Charge −1/3 Quarks and Charged Leptons with Exotic Fermions in E6
A way is suggested to understand why the average masses of (d, s, b) quarks are smaller than those of (u, c, t) quarks. In contrast to previously proposed mechanisms relying on different Higgs boson vacuum expectation values or different Yukawa couplings, the mass difference is explained as a consequence of mixing of (d, s, b) with exotic quarks implied by the electroweak-strong unification gro...
