O ( α 2 s ) corrections to fully - differential top quark decays
نویسندگان
چکیده
We describe a calculation of the fully-differential decay rate of a top quark to a massless b-quark and a lepton pair at next-to-next-to-leading order in perturbative QCD. Technical details of the calculation are discussed and selected results for kinematic distributions are shown.

Electroweak Penguin Contributions to Non - Leptonic ∆ F = 1 Decays at NNLO
We calculate the O(αs) corrections to the Z-penguin and electroweak box diagrams relevant for non-leptonic ∆F = 1 decays with F = S,B. This calculation provides the complete O(αWαs) and O(αWαs sin θWmt ) corrections (αW = α/ sin θW ) to the Wilson coefficients of the electroweak penguin four quark operators relevant for non-leptonic Kand B-decays. We argue that this is the dominant part of the ...
متن کاملComplete QCD Corrections to Hadronic Z – Decays in Order α
Corrections of order α s for the axial singlet contributions for the decay rate of the Z-boson into hadrons are evaluated in the limit of the heavy top quark mass. Combined with recently finished O(α s ) calculations of the non-signlet corrections, the new results directly lead us to the first complete O(α s ) prediction for the total hadronic decay rate of the Z-boson. The new O(α s ) term in ...
متن کاملThe Supersymmetric QCD Radiative Corrections to Top Quark Semileptonic Decays
The one-loop supersymmetric QCD corrections to the top quark semileptonic decays t → b l̄ νl are considered. The corrections are found to reduce the decay width. In the still acceptable parameter space the corrections to the percentage change in top quark semileptonic decay width can reach the level of -0.7%. PACS numbers: 11.30.Pb, 12.38.Bx, 14.65.Ha Keyword(s): SUSY QCD, RADIATIVE CORRECTIONS,...
متن کاملTop quark inclusive differential distributions.
The inclusive transverse momentum and rapidity distributions for top quark production at the Fermilab Tevatron are presented both in order α 3 s in QCD and using the resummation of the leading soft gluon corrections in all orders of QCD perturbation theory. The resummed results are uniformly larger than the O(α 3 s) results for both distributions.
متن کاملNon-singlet Corrections of O(α 2 S G F M
The partial decay rate of the Z boson into bottom quarks constitutes an important decay channel. This is mainly due to the virtual presence of the top quark in the loop diagrams giving rise to correction factors which are quadratic in the top quark mass. At one-and two-loop order it turned out that the leading term in the heavy-top expansion leads to very good approximations to the exact result...
