A comparative study of jet algorithms in the energy range from CESR to LEP

A comprehensive study of all the jet algorithms used at experiments is performed. The author presents some new algorithms in order to exhaust all the possibilities of defining resolvable jets in the context of present understanding. The author studies the hadronization effects exhibited by all these algorithms at various energies: ranging from CESR energy (ie. 10 GeV) to LEP energy (ie 90 GeV). As the hadronization corrections decrease in size with rise in energy, the jets are an attractive tools for testing perturbative QCD at LEP energy. To test perturbative QCD at the low energy end where it breaks down is very crucial to build a coherent understanding of strong interactions. Due to the large hadronization corrections, study of jets at CESR energy becomes a difficult task. The author discusses the possibilities of testing perturbative QCD at CESR energy using jets, and develop a suitable jet algorithm to be used at this energy
