hep-ph/9512409 POLARIZED TOP QUARKS ∗†
نویسندگان
چکیده
Recent calculations are presented of top quark polarization in t ¯ t pair production close to threshold. S–P-wave interference gives contributions to all components of the top quark polarization vector. Rescattering of the decay products is considered. Moments of the fourmomentum of the charged lepton in semileptonic top decays are calculated and shown to be very sensitive to the top quark polarization.

The Fermilab top quark analysis is heavily dependent on the assumption of standard model backgrounds only. In the light gluino scenario, the stop quarks lie near the top in mass and their decays can influence the resulting top quark mass by an amount that is not small relative to the currently quoted errors. Several slight anomalies in the top quark analysis find a natural explanation in the li...
متن کاملAzimuthal angular dependence of decay lepton in e + e − → tt̄
We discuss top quark production and its subsequent decay for searching new physics at lepton colliders. The angular dependence of the decay leptons is calculated including both QCD corrections and anomalous γ/Z− tt̄ couplings. The off-diagonal spin basis for the top and anti-top quarks is shown to be useful to probe the anomalous couplings. TU-600 HUPD-0004 hep-ph/0008065 August 2000

We summarize recent results on QCD corrections to various observables in semilep-tonic b quark decays. For massless leptons in the final state we present effects of such corrections on triple differential distribution of leptons which are important in studies of polarized b quark decays. Analogous formulas for distributions of neu-trinos are applicable in decays of polarized c quarks. In the ca...
متن کاملNotes on the Soft-Collinear Effective Theory
Contents 1 Introduction to SCET 4 1. 1 Introduction to SCET These notes provide reading material on the Soft-Collinear Effective Theory (SCET) for Chrisitian's SCET Lectures in TASI 2013. They also served as lecture notes for Iain's 2013 EFT course taught at MIT. The notes assume some familiarity with various basic effective field theory (EFT) concepts, including power counting with operator di...

The polarization dependent momentum distributions of top quarks and their decay products are calculated for t ¯ t production at future e + e − colliders with polarized beams. The Green function formalism is applied to this reaction near energy threshold. The Lippmann–Schwinger equations for the S-wave and P-wave Green functions are solved numerically for the QCD chromostatic potential given by ...
