Leading QCD Corrections to Scalar Quark Contributions to Electroweak Precision Observables
A. Djouadi, P. Gambino, S. Heinemeyer +3
In the supersymmetric extension of the Standard Model we derive the two-loop QCD corrections to the scalar quark contributions to the electroweak precision observables entering via…
SUSY Higgs Boson Decays into Scalar Quarks: QCD Corrections
A. Arhrib, A. Djouadi, W. Hollik +1
In supersymmetric theories, the decays of the neutral CP-even and CP-odd as well as the charged Higgs bosons into scalar quarks, in particular into top and bottom squarks, can be d…
Supersymmetric contributions to electroweak precision observables: QCD corrections
A. Djouadi, P. Gambino, S. Heinemeyer +3
We calculate the two-loop QCD correction to the scalar quark contributions to the electroweak gauge-boson self-energies at zero momentum-transfer in the supersymmetric extension of…
QCD Corrections to Scalar Quark Decays
A. Djouadi, W. Hollik, C. Junger
In supersymmetric theories, the main decay modes of scalar quarks are decays into quarks plus charginos or neutralinos, if the gluinos are heavy enough. We calculate the O() Q…
QCD Corrections to the Top Decay Mode $t \ra \tilde{t} χ^0$
A. Djouadi, W. Hollik, C. Junger
In supersymmetric theories, the top quark can decay into its scalar partner plus a neutralino, with an appreciable rate. We calculate the QCD corrections to this decay mod…
Loop Induced Higgs Boson Pair Production at e+e- Colliders
A. Djouadi, V. Driesen, C. Junger
We analyse the loop induced production of Higgs boson pairs at future high--energy colliders, both in the Standard Model and in its minimal supersymmetric extension. The c…
