 +====== TTP02-41 Towards Order alpha_s^4 Accuracy in tau-decays ====== 
 +   <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.
