CHARGINOS AND NEUTRALINOS AT ee LINEAR COLLIDERS
In the Minimal Supersymmetric Standard Model (MSSM) the light chargino χ̃±1 and the two light neutralinos χ̃01 and χ̃ 0 2 are expected 1 to be among the lightest supersymmetric particles. The lightest neutralino χ̃01 is commonly assumed to be the lightest SUSY particle (LSP), stable in the R-parity conserving case, and invisible. The chargino and neutralino masses are given in terms of the fundamen...
متن کاملTesting Higgs Self-couplings at ee 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-couplings, as predicted, for instance, in the Standard Model or in supersymmetric theories. The couplings can be probed in multiple Higgs production at highluminosity ee linear colliders. Comple...
متن کاملSlepton Production at ee and e−e− Linear Colliders
High-precision analyses are presented for the production of scalar sleptons, selectrons and smuons in supersymmetric theories, at future e+e− and e−e− linear colliders. Threshold production can be exploited for measurements of the selectron and smuon masses, an essential ingredient for the reconstruction of the fundamental supersymmetric theory at high scales. The production of selectrons in th...
متن کاملSTRONGLY INTERACTING VECTOR BOSONS AT TeV ee LINEAR COLLIDERS
In the absence of light Higgs bosons, the W and Z bosons become strongly interacting particles at energies of about 1 TeV. If the longitudinal W ,Z components are generated by Goldstone modes associated with spontaneous symmetry breaking in a new strong interaction theory, the quasi-elastic W ,Z scattering amplitudes can be predicted as a systematic chiral expansion in the energy. We study the ...
متن کاملSlepton Production at ee and e−e− Linear Colliders: Addendum
Complementing the preceding study of charged scalar leptons, the sector of the neutral scalar leptons, sneutrinos, is investigated in a high-precision analysis for future e + e − linear colliders. The theoretical predictions for the cross-sections are calculated at the thresholds for non-zero widths and in the continuum including higher-order corrections at the one-loop level. Methods for measu...
