Are there indications of compositeness of leptons and quarks in CERN LEP data?
Erik Elfgren, Sverker Fredriksson
The ``preon-trinity'' model for the compositeness of leptons, quarks and heavy vector bosons predicts several new heavy leptons and quarks. Three of them can be produced in $e^{+}e…
Using Monte Carlo to optimize variable cuts
Erik Elfgren
A Monte Carlo method to optimize cuts on variables is presented and evaluated. The method gives a much higher signal to noise ratio than does a manual choice of cuts.
Heavy and Excited Leptons in the OPAL Detector?
Erik Elfgren
This M.Sc. thesis describes a search for exotic leptons. The search has been performed using data from the OPAL detector at the Large Electron Positron collider at CERN. The total…
Detection of a Hypercharge Axion in ATLAS
Erik Elfgren
This Master of Science thesis treats the hypercharge axion, which is a hypothetical pseudo-scalar particle with electroweak interactions. First, the theoretical context and the mot…
