Abstract: The recent developments in theoretical calculations (code NLOJET++) allow us to evaluate the 3-jet observables at the next-to-leading order precision. In this diploma thesis we investigate the potential of using 3-jet observables for the measurement of strong coupling s at hadron colliders. First, we analyze the inclusive jet cross section measured by DO Collaboration, determine s and demonstrate its running in a similar way as was previously done by CDF Collaboration. In the second part of the thesis, we analyze the DO measurement of dijet azimuthal decorrelations. With this choice of 3-jet observable we were able to achieve a better precision of s than in the previous s measurements based on the inclusive jet production.
