Supersymmetry parameter analysis: SPA convention and project

High-precision analyses of supersymmetry parameters aim at reconstructing the fundamental supersymmetric theory and its breaking mechanism. A well defined theoretical framework is needed when higher-order corr...

Chargino and neutralino decays revisited

We perform a comprehensive analysis of the decays of charginos and neutralinos in the minimal supersymmetric standard model where the neutralino \(\chi_1^0\) is assumed to be th...

Reconstructing the chargino system at \(e^+e^-\) linear colliders

In most supersymmetric theories charginos, \(\tilde{\chi}^\pm_{1,2}\) , belong to the class of the lightest supersymmetric particles. The chargino system can be reconstructed com...

Production of neutral Higgs-boson pairs at LHC

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 multiple production of Higgs bos...

Testing Higgs self-couplings at \(e^+e^-\) linear colliders

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 and quadrilinear self-coupling...

Determining SUSY parameters in chargino pair-production in \(e^+e^-\) collisions

In most supersymmetric theories, charginos \(\tilde{\chi}^\pm_{1,2}\) , mixtures of charged color-neutral gauginos and higgsinos, belong to the class of the lightest supersymmetr...

Chargino pair production in \(e^+e^-\) collisions

Charginos \(\chi_1^\pm\) are expected to be the lightest observable supersymmetric particles in many supersymmetric models. We present a procedure which will allow to determine ...

The Higgs-photon-Z boson coupling revisited

We analyze the coupling of CP-even and CP-odd Higgs bosons to a photon and a Z boson in extensions, of the Standard Model. In particular, we study in detail the effect of charged Higgs bosons in two-Higgs doub...

The coupling of the lightest SUSY Higgs boson to two photons in the decoupling regime

We analyze the contribution of the SUSY particles to the coupling of the lightest Higgs boson to two photons in supersymmetric theories. We discuss to what extent these contributions can be large enough to all...
