Abstract
We set up a formalism for calculating the O(alpha(s)) corrections to t he process ppBAR --> W+X --> taunu(tau)XBAR with spin-correlated tau d ecays to leptons and mesons. Our results axe applicable to Monte Carlo integration, which allows easy construction of any desired observable at next-to-leading-log level, and the possibility to include experime ntal cuts. Our results are applied explicitly to the decay modes tauBA R --> nu(tau)enu(e)BAR, tauBAR --> nu(tau)pi+BAR, and tau --> nu(tau)p i+pi0BAR; other decay modes may be included in a straightforward fashi on. We show results for transverse momentum and rapidity variables in leading-log and next-to-leading-log approximations; the leptonic obser vables are compared to similar observables from direct W --> enu(e)BAR .
