Jets and Event Shape Studies in ep-collisions at HERA

Abstract

The results of complementary tests of perturbative QCD in DIS at large centre-of-mass energies at HERA are presented. The analysis of event shape variables allows for the investigation of approaches to understand aspects of non-perturbative QCD such as the formation of the hadronic final state. The strong coupling constant, ${\alpha }_s$, is extracted from both inclusive jet cross sections and dijet rates and is found to be competitive with the world average.
