Energy dependence of event shapes and of alpha(s) at LEP 2

Energy dependence of event shapes and of alpha(s) at LEP 2

Infrared and collinear safe event shape distributions and their mean values are determined using the data taken at five different centre of mass energies above MZ with the DELPHI detector at LEP. From the event shapes, the strong coupling αS is extracted in θ(αS2), NLLA and a combined scheme using h...
