Stop Decays in Susy-qcd *

چکیده

The partial widths are determined for stop decays to top quarks and gluinos, and gluino decays to stop particles and top quarks (depending on the masses of the particles involved). The widths are calculated including one-loop SUSYQCD corrections. The radiative corrections for these strong-interaction decays are compared with the SUSY-QCD corrections for electroweak stop decays to quarks and neutralinos/charginos and top-quark decays to stops and neutralinos. partially supported by EU contract CHRX–CT–92–0004 Fellow of the Royal Dutch Academy of Arts and Sciences

SUSY-QCD corrections to stop and sbottom decays into Higgs bosons

We calculate the O(αs) SUSY–QCD corrections to the widths of stop and sbottom decays into Higgs bosons within the Minimal Supersymmetric Standard Model. We give the complete analytical formulae paying particular attention to the on–shell renormalization of the soft SUSY–breaking parameters. We also perform a detailed numerical analysis of both stop and sbottom decays. We find that the SUSY–QCD ...

B?J/?(?,K) Decays within QCD Factorization Approach

We used QCD factorization for the hadronic matrix elements to show that the existing data, in particular the branching ratios BR ( ?J/?K) and BR ( ?J/??), can be accounted for this approach. We analyzed the decay within the framework of QCD factorization. We have complete calculation of the relevant hard-scattering kernels for twist-2 and twist-3. We calculated this decays in a special scale ...

واپاشیهای پنگوئن درکوارک b

In this research, we are going to study the QCD penguin structure and calculate the second order approximation. The amplitude of decays related to QCD penguin in the quark model up to the first and second orders were calculated. We calculated the amplitude of QCD penguin on lowest order of αs for the first order of the decay processes b→qkg→qkqiqj and for the second order of the decay processes...

The role of electroweak penguin and magnetic dipole QCD penguin on hadronic b Quark Decays

This research, works with the effective Hamiltonian and the quark model. Using, the decay rates of matter-antimatter of b quark was investigated. We described the effective Hamiltonian theory which was applied to the calculation of current-current (Q1,2), QCD penguin (Q3,…,6), magnetic dipole (Q8) and electroweak penguin (Q7,…,10) decay rates. The gluonic penguin structure of hadronic decays ...

SUSY-QCD Decays of Squarks and Gluinos

The partial widths are determined for squark decays to gluinos and quarks, and gluino decays to squarks and quarks, respectively. The widths are calculated including one-loop SUSY-QCD corrections. The corrections amount to +30% to +50% for squark decays and −10% to +10% for gluino decays. We have derived the results in the DR and MS renormalization schemes, and we have demonstrated explicitly t...
