| | <hidden TTP02-41 Towards Order alpha_s^4 Accuracy in tau-decays > Recently computed terms of orders O(\alpha_s^4 n_f^2) in the |
| | perturbative series for the tau decay rate, and similar (new) strange |
| | quark mass corrections, are used to discuss the validity of various |
| | optimization schemes. The results are then employed to arrive at |
| | improved predictions for the complete terms order O(\alpha_s^4) and |
| | O(\alpha_s^5) in the massless limit as well as for terms due to the |
| | strange quark mass. Phenomenological implications are presented. |
