Top-quark Pole Mass

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...

Top 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.

Top quark mass measurements at D0

We present the most recent measurements of the mass of the top quark at D0 using proton-antiproton collisions at √ s = 1.96 TeV at the Fermilab Tevatron collider. The world average for the mass of the top quark is 170.9 ± 1.8 GeV/c.

Precision 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 ...
