SUSY contributions to Rb and top quark decay.
Stop contributions to radiative corrections to Rb and the top quark decay are analysed over the relevant MSSM parameter space. One sees a 30% increase in the former along with a similar drop in the latter in going from the higgsino dominated to the mixed region. Consequently one can get a viable SUSY contribution to Rb within the constraint of the top quark data only in the mixed region, corres...
متن کاملSUSY CONTRIBUTIONS TO Rb AND TOP DECAY
while it is suppressed for the latter by the U(1) coupling factor ∼ sin θW . Thus the large b vertex (6) favours large higgsino component of W̃1 corresponding to the higgsino dominated region (|μ| M2); but the large Z vertex (7) favours large gaugino components of W̃1 corresponding to the gaugino dominated region (|μ| M2) [5]. As we shall see below, the combined requirements of large b and Z vert...
متن کاملImpact of SUSY-QCD corrections on top quark decay distributions
We compute the supersymmetric QCD corrections to the decay distribution of polarized top quarks for the semileptonic decay mode t(↑) → blνl . As a byproduct, we reinvestigate the SUSY-QCD corrections to the total decay width Γ(t → W +b) and resolve a discrepancy between two previous results in the literature.
متن کاملSoft SUSY breaking contributions to proton decay
We show that in supersymmetric grand unified theories new effective D=4 and D=5 operators for proton decay are induced by soft SUSY-breaking terms, when heavy GUT gauge bosons are integrated out, in addition to the standard D=6 ones. As a result, the proton lifetime in gauge mediated channels can be enhanced or even suppressed depending on the size of the heavy Higgses soft terms.
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...
