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…
Impact of e^+ and e^- Beam Polarization on Chargino and Neutralino Production at a Linear Collider
G. Moortgat-Pick, A. Bartl, H. Fraas +1
We study the production processes e^+ e^- -> chi^+_i chi^-_j, i,j=1,2, and e^+ e^- -> chi^0_m chi^0_n, m,n=1,...,4, working out the advantages of polarizing both beams. For e^+ e^-…
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…
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…
