Resonant second generation slepton production at the tevatron
… topologies, are chosen to search for resonant slepton production and for the pair and associated production of gauginos. To the resonant slepton production three different signal channels contribute; (i) ~mu->~chi^0_1 mu, (ii) ~mu->~chi^0_2 mu and (iii) ~nu_mu->~chi^+-_1 mu. These three …

Symbolic computation of electron-proton to slepton-squark scattering cross sections based on a left-right supersymmetric extension of the standard model
… are written down, and the production of sleptons and squarks resulting from the t-channel exchange of neutralinos and charginos in electron-proton scattering is analyzed. The symbolic programming language Mathematica ® , is used to develop a program to generate a symbolic representation …

Towards a reconstruction of the SUSY seesaw model
… namely rare flavor violating decays of leptons, slepton pair production processes at linear colliders and slepton mass differences. This is a challenging task as there is an intricate dependence of the observables on the unknown seesaw, light neutrino and mSUGRA parameters. In order to separate …

Brane worlds, brane worlds : it's party time : excellent
… Anomaly mediation, however, predicts negative slepton mass squardes. In this thesis we will try to address this problem by providing positive contributions to the slepton masses, through higher order SUSY breaking effects stemming from having additional heavy fields in the theory. We will also …

A Search for Sleptons with Intermediate Lifetimes in e+e- Collisions at sqrt(s)=189-209 GeV
In dieser Arbeit wird eine Suche nach Sleptonen mit mittlerer Lebensdauer (approx. 10^(-11)-10^(-9)s) mit dem OPAL-Detektor am LEP-Speicherring vorgestellt fuer den Fall, dass das Slepton das NLSP (next-to-lightest supersymmetric particle) ist. Sleptonen mit mittlerer Lebensdauer werden im Rahmen …

Holly Pacey and the Half-Spin Particles: Searching for new physics with leptons at the ATLAS experiment
… up to 420 GeV, as well as excluding direct slepton production with slepton masses up to 700 GeV and chargino pair production decaying via sleptons or sneutrinos with chargino masses up to 1 TeV. The third search uses an innovative technique to pursue signs of lepton charge-flavour asymmetry …

Supersymmetry Breaking: Models of Gauge Mediation with Gauge Messengers
… that a mild splitting between scalar (squark and slepton) and gaugino masses exists. After this, a general argument showed that in fact gaugino masses are always significantly smaller than scalar masses if the universe is perturbatively stable. This arguments suggests that any viable vacuum should …
