Electroweak Corrections to the Top Quark Decay
We have calculated the one-loop electroweak corrections to the decay t→ bW, including the counterterm for the CKM matrix elements Vtb. Previous calculations used an incorrect δVtb that led to a gauge dependent amplitude. However, since the contribution stemming from δVtb is small, those calculations only underestimate the width by roughly one part in 10. PACS number(s): 12.15.Lk, 11.10.Gh, 12.1...
متن کاملB-hadron production in top quark decay
We present the energy distribution of b-flavoured hadrons in top quark decay using the PYTHIA and HERWIG event generators, which we tune to LEP and SLD data. We find that fitting the string and cluster models is essential to reproduce the ee data and to reliably predict B-hadron production in top decay. We also compare the PYTHIA and HERWIG results with the ones yielded by resummed calculations...
متن کاملMeasurements of top quark decay properties
I report on measurements of the properties of the top quark using data collected by the CDF and DØ detectors during Run II of the Fermilab Tevatron. The helicity of the W boson arising from top quark decay, the top quark decay branching ratios, and the top quark charge have all been measured, and the results in all cases are consistent with standard model expectations.
متن کاملQcd Flavour Changing Top Quark Decay
We present a detailed and complete calculation of the gluino and scalar quarks contribution to the flavour-changing top quark decay into a charm quark and a photon, gluon, or a Z 0 boson within the minimal supersymmetric standard model including flavour changing gluino-quarks-scalar quarks couplings in the right-handed sector. We compare the results with the ones presented in an earlier paper w...
متن کاملNew angles on top quark decay to a charged Higgs
To properly discover a charged Higgs Boson (H±) requires its spin and couplings to be determined. We investigate how to utilize tt̄ spin correlations to analyze the H± couplings in the decay t → bH → bτντ . Within the framework of a general TwoHiggs-Doublet Model, we obtain results on the spin analyzing coefficients for this decay and study in detail its spin phenomenology, focusing on the limit...
