Direct Top Quark Production at Hadron Colliders as a Probe of New Physics
We examine the effect of an anomalous flavor changing chromomagnetic moment which allows direct top quark production (two partons combining into an unaccompanied single top quark in the schannel) at hadron colliders. We consider both t-c-g and t-u-g couplings. We find that the anomalous charm quark coupling parameter κc/Λ can be measured down to .06 TeV (.009 TeV) at the Tevatron with the Main ...
متن کاملTop Quark Physics: Summary
This talk summarizes recent progress in top quark physics studies for high energy linear electron-positron colliders as presented at the LCWS2000 Workshop at Fermilab. New results were presented for top pair production at threshold and in the continuum, as well as for top production at γγ colliders.
متن کاملBottom and Top Physics
The production of bottom quarks at the SSC and the formalism and phenomenology of observing CP violation in B meson decays is discussed. The production of a heavy t quark which decays into a real W boson, and what we might learn from its decays is examined.
متن کاملDØ Top Physics
The top quark, which completes the quark sector of the SM, was discovered in 1995 at the Tevatron by the CDF and DØ Collaborations [1]. Being the heaviest of all quarks with a mass of 178.0 ± 4.3 GeV/c [2], it couples most strongly to the Higgs boson, and its lifetime of ≈ 4 · 10 s means that it is the only quark that decays before it can hadronise, preserving spin information, and providing a ...
