Implications of CP and CPT for production and decay of Majorana fermions
G. Moortgat-Pick, H. Fraas
The consequences of CP- and CPT-invariance for production and subsequent decay of Majorana fermions are analytically studied. We derive general symmetry relations for the spin dens…
Production of Charginos, Neutralinos, and Third Generation Sfermions at an e+e- Linear Collider
A. Bartl, H. Eberl, H. Fraas +4
We discuss the production of charginos, neutralinos, and third generation sfermions in annihilation in the energy range TeV. We present numerical predic…
Beam Polarization and Spin Correlation Effects in Chargino Production and Decay
G. Moortgat-Pick, A. Bartl, H. Fraas +1
We study chargino production e^+ e^- -> chi^+_1 chi^-_1 and the subsequent leptonic decay chi^-_1\to chi^0_1 e^- nu_e including the complete spin correlations between production an…
Neutralino Production with Polarized Beams in Extended Supersymmetric Models
S. Hesselbach, F. Franke, H. Fraas
We discuss associated neutralino production e^+ e^- --> \tildeχ^0_1 \tildeχ^0_2 with both beams polarized in the MSSM, NMSSM and an E_6 model. It is shown that neutralinos with a l…
Exploiting Spin Correlations in Neutralino Production and Decay with Polarized e^- and e^+ Beams
G. Moortgat-Pick, A. Bartl, H. Fraas +1
We study the production process e^+ e^- -> chi^0_1 chi^0_2 and the subsequent decay chi^0_2 -> chi^0_1 l^+ l^- with polarized e^+ and e^- beams, including the spin correlations bet…
Possible Test of the GUT Relation between and in Electron-Photon Scattering
C. Blöchinger, H. Fraas
We investigate associated production of selectrons and the lightest neutralino (LSP) in the process e^- + gamma --> neutralino_1 + selectron_{L/R} with the selectron subsequently d…
