Top quark production near threshold and the top quark mass
We consider top-anti-top production near threshold in e+e− collisions, resumming Coulomb-enhanced corrections at next-to-next-to-leading order (NNLO). We also sum potentially large logarithms of the small top quark velocity at the next-toleading logarithmic level using the renormalization group. The NNLO correction to the cross section is large, and it leads to a significant modification of the...
متن کاملTop quark mass determination near tt̄ threshold at lepton colliders ∗
Top quark mass determination near t ¯ t threshold at lepton colliders * Abstract Future e + e − linear colliders will enable us to determine the top quark mass with high accuracy from the measurement of the 1S peak position of (remnant of) toponium. The estimated statistical error in this measurement is about 50 MeV with integrated luminosity of 30 fb −1. We calculate O(α 5 s m) corrections to ...
متن کاملTop Quark Mass and Supersymmetry
We summarize the expectations for the top quark mass in supersymmetric models and discuss the potential implications of its value measured by the CDF group in Fermilab.
متن کاملTop Quark Mass Measurements at the Tevatron
The general strategy, as well as channel-specific details, applied to the measurement of the top quark mass at the Tevatron in Run I are reviewed, and the combination of the results obtained by the CDF and DØ collaborations presented. The accelerator and detector upgrades for Run II are described, and expected improvements in the systematic uncertainties on the measurement evaluated.
متن کاملIndirect determinations of the top quark mass
We give a complete analysis of indirect determinations of the top quark mass in the Standard Model by introducing a systematic procedure to identify observables that receive quantum corrections enhanced by powers of Mt. We discuss how to use flavour physics as a tool to extract the top quark mass. Although present data give only a poor determination, we show how future theoretical and experimen...
