Light Scalar Top Quarks and Supersymmetric Dark Matter
C. Boehm, A. Djouadi, M. Drees
A stable neutralino , assumed to be the lightest supersymmetric particle, is a favored particle physics candidate for the cosmological Dark Matter. We study co-annihilation…
Report of the Beyond the Standard Model Working Group of the 1999 UK Phenomenology Workshop on Collider Physics (Durham)
B. C. Allanach, J. J. van der Bij, A. Dedes +23
The Beyond the Standard Model Working Group discussed a variety of topics relating to exotic searches at current and future colliders, and the phenomenology of current models beyon…
Supersymmetry Effects on High-Precision Electroweak Observables
Abdelhak Djouadi
I summarise the virtual effects of the new particles predicted by supersymmetric extensions of the Standard Model on the high-precision electroweak observables measured at LEP/SLC,…
Higgs Particles at Linear e+e- Colliders: theoretical issues
Abdelhak Djouadi
I summarize the prospects for discovering and studying the properties of Higgs particles at future high-energy and high-luminosity linear colliders. I will focus on the Hi…
Determining SUSY Parameters in Chargino Pair Production in e^+e^- Collisions
S. Y. Choi
In most supersymmetric theories, charginos belong to the class of the lightest supersymmetric particles and they are easy to observe at e^+e^- colliders. By mea…
Stop-Stop-Higgs Production at future Linear Collider
A. Djouadi, J. -L. Kneur, G. Moultaka
In the Minimal Supersymmetric Standard Model, the cross section for the associated production of the lightest neutral Higgs boson with the lightest top squark pairs can be rather s…
Decays of the Lightest Top Squark
C. Boehm, A. Djouadi, Y. Mambrini
We analyze higher order decay modes of the lightest top squark in the Minimal Supersymmetric extension of the Standard Model (MSSM), where the lightest SUSY particle…
Production of Neutral Higgs-Boson Pairs at LHC
A. Djouadi, W. Kilian, M. Muhlleitner +1
The reconstruction of the Higgs potential in the Standard Model or supersymmetric theories demands the measurement of the trilinear Higgs couplings. These couplings affect the mult…
Impact of the SUSY Decays on the Search for the MSSM Higgs bosons at the LHC
A. Djouadi
In the context of the Minimal Supersymmetric extension of the Standard Model, we discuss the impact of the decays of the neutral Higgs bosons into supersymmetric particles, chargin…
Testing Higgs Self-couplings at e^+e^- Linear Colliders
A. Djouadi, W. Kilian, M. Muhlleitner +1
To establish the Higgs mechanism sui generis experimentally, the self-energy potential of the Higgs field must be reconstructed. This task requires the measurement of the trilinear…
Associated Production of Higgs Bosons with Scalar Quarks at Future Hadron and Colliders
A. Djouadi, J. -L. Kneur, G. Moultaka
We analyze the production of neutral Higgs particles in association with the supersymmetric scalar partners of the third generation quarks at future high--energy hadron colliders […

Top Squark Effects on Higgs Boson Production and Decays at the LHC
Abdelhak Djouadi
In the Minimal Supersymmetric Standard Model, one of the scalar top quarks can be relatively light and its couplings to Higgs bosons strongly enhanced. I will discuss two consequen…
