Quest for Isolated Fractionally Charged Particles – Physics Beyond the Standard model CERN

The quantization of electric charge – that electric charge comes in integer multiples of the electron charge - is an empirically well supported idea. However, the Standard Model does not impose charge quantization. In order to enforce quantization of charge, physics beyond the Standard Model is necessary. This observation has stimulated inquiry into mechanisms whereby charge quantization might be violated. Particles with small fractional charge appear as a natural consequence of many of these mechanisms.

The search for a fractionally charged particle has progressed through the efforts of many direct experiments and indirect observations over many years.

This talk will describe how we searched for fractionally charged particles using proton interactions at CERN (European Center for Nuclear Research – Geneva, Switzerland) in fixed target experiment, how to be involved in Particle Physics Experiment at CERN.
