Is it possible to detect the η' → e+e- decay? : A simulation of the η' decay from e+e- collisions

Hamnevik, Daniel January 2014 (has links)
Decays of light, pseudoscalar mesons into lepton pairs are one possible way of detecting physics beyond the Standard Model. This thesis will focus on the η' → e+e- decay, because only few experiments have studied this decay. By the use of a basic simulation, the feasibility of conducting a search for the  η' → e+e- decay at DAΦNE, a electron-positron collider in Frascati, Italy, was investigated. The simulation implements an idea from previous experiments, where the η' decay was investigated through the e+e- → η' → X process. The results of the simulation show that experiments at DAΦNE could produce an observable signal of the process when the produced η' decays into one of the most probable decay modes. However, in order to draw a definite conclusion, a more detailed study is needed. / Sönderfallet av lätta, pseudoskalära mesoner till ett par av leptoner är ett möjligt sätt att detektera fysik bortom Standardmodellen. Detta examensarbete fokuserar på η’ → e+e- sönderfallet, på grund av att få experiment har studerat detta sönderfall. Genom att använda en enkel simulering, undersöktes möjligheten att studera η’ → e+e- sönderfallet vid DAΦNE, en elektron-positron accelerator i Frascati, Italien. Simuleringen följde samma genomförande som tidigare experiment, där η’ sönderfallet undersöktes genom e+e- → η’ → X processen. Resultaten av simuleringen visar på att experiment vid DAΦNE kan producera en detekterbar signal av processen då de producerade η’ sönderfaller till de mest troliga sönderfallen. På grund av begränsningarna i den utförda simulationen, behöver dock en mer detaljerad studie göras för att dra definitiva slutsatser.
