Description
I present the results of a recent work, were different, yet legitimate, resummation prescriptions are considered for the calculation of the thrust distribution in e+e- collisions. In particular we consider differences in the resummation performed in the so called conjugate (Laplace transform) space with respect to the direct one, and differences that arises when certain commonly adopted approximations used in the conjugate space approach are avoided. We showed that these different approaches may lead to non-negligible numerical differences.
