An improved theoretical prediction for the 2-jet rate in e+e- annihilation

We show that an Ansatz to resum all leading and next-to-leading logarithms in the theoretical prediction for the 2-jet rate in e+e- -> hadrons, where jets are defined with the k_t-algorithm, is consistent with a full O(alpha_s^2) calculation done by Monte Carlo integration. From the asymptotic be...

description We show that an Ansatz to resum all leading and next-to-leading logarithms in the theoretical prediction for the 2-jet rate in e+e- -> hadrons, where jets are defined with the k_t-algorithm, is consistent with a full O(alpha_s^2) calculation done by Monte Carlo integration. From the asymptotic behaviour of the full O(alpha_s^2) calculation we extract the subleading coefficient G_21 and the constant C_2.
