We present an up-to-date overview of the problem top quark mass determination. assess need for precision in extraction LHC era together with main theoretical and experimental issues arising collect document existing results on determination at hadron colliders map prospects future $$e^+e^-$$ colliders. a collection estimates ultimate various methods LHC.
Data from high-energy physics (HEP) experiments are collected with significant financial and human effort mostly unique. An inter-experimental study group on HEP data preservation long-term analysis was convened as a panel of the International Committee for Future Accelerators (ICFA). The formed by large collider-based investigated technical organisational aspects preservation. intermediate report released in November 2009 addressing general issues HEP. This paper includes extends report. It...

I report on the combination of measurements from CDF and D0 helicity fractions W bosons top quark decays.The result, when both longitudinal ( f 0 ) right-handed + are allowed to float, is = 0.722 ± 0.081 [± 0.062 (stat.)± 0.052 (syst.)]and -0.033± 0.046 0.034 0.031 (syst.)],consistent with Standard Model (SM) expectation.When one fraction fixed its SM value results for other 0.682 0.057 0.035 -0.015± 0.018 0.030 (syst.)].
The capabilities of 14 TeV and 33 pp colliders for discovering vector-like B quarks is examined. These studies were carried out as part the Snowmass Community Planning exercise.
Many high-energy physics analyses require the presence of leptons from $W$, $Z$, or $H$ boson decay. For these analyses, signatures that mimic such present a `fake lepton' background must be estimated. Since magnitude this depends strongly upon details detector response, it can difficult to estimate with simulation. One data-driven approach is `matrix method', in which two categories are defined (`loose' and `tight'), tight category being subset loose category. Using populations each...
▪ Abstract We review the direct measurements of top quark mass M t using sample [Formula: see text] events collected by DØ and CDF experiments at Fermilab. Measurements in lepton plus jets, dilepton, all-hadronic decay modes are reviewed, as is combination results to yield current world average = 174.3 ± 3.2 (stat.) 4.0 (syst.) GeV/c 2 . close estimating precision attainable with future data sets Fermilab Large Hadron Collider.
A review is presented of the current experimental status top quark sector standard model. The measurements summarized include searches for electroweak single production, latest results on ttbar production cross section, and new physics in decay. In addition, recent measurement mass to a precision 0.7% highlighted
The search for the Higgs boson, both in context of standard model and extensions to it, has been a key focus during Run II Tevatron. I report on status these searches, which are highlighted by evidence at 3 deviation level SM its $b\bar{b}$ decay mode, strongest direct date fermionic couplings boson.
