Optimized perturbation theory applied to jet cross sections in e + e - annihilation
Abstract
The optimized perturbation theory proposed by Stevenson to deal with coupling constant scheme dependence is applied to the calculation of π tot and jet multiplicities in e + e - annihilation. The results are compared with those of simple perturbation theory and with recent experimental cluster multiplicities.
