The e-e- mode would be a straight forward extension to the currently planed International Linear Collider, planned to operate in e+e- mode. The low background in this mode may prove advantageous in the study of CP- and Lepton Flavour Violtation. In this work a CP sensitive observable based on transverse beam polarisation is introduced and the impact of neutralino mixing on the total cross section in cas of non-vanishing CP-violtating phases is studied in representative scenarios including non-GUT scenarios. Additionally, the mixing of sleptons is studied in the context of LFV, an analytical approximation is developed, and possible background free measurements of these effects are investigated.}, subject = {Supersymmetrie}, language = {en} } @phdthesis{Kittel2004, author = {Kittel, Olaf}, title = {CP violation in production and decay of supersymmetric particles}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-12767}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2004}, abstract = {In dieser Dissertation untersuchen wir CP verletzende Effekte von MSSM-Phasen in Produktion und Zwei-Teilchen-Zerfaellen von Neutralinos, Charginos und Sfermionen.

Wir zeigen numerische Ergebnisse fuer Elektron-Positron-Kollisionen an einem zukuenftigen Linearbeschleuniger mit einer Energie von 500 - 800 GeV, hoher Luminositaet und longitudinal polarisierten Strahlen.}, subject = {Supersymmetrisches Teilchen}, language = {en} }
