Abstract

We set up a formalism for calculating the O(α𝑠) corrections to the process pp¯→𝑊+X→τ¯ντX with spin-correlated τ decays to leptons and mesons. Our results are applicable to Monte Carlo integration, which allows easy construction of any desired observable at next-to-leading-log level, and the possibility to include experimental cuts. Our results are applied explicitly to the decay modes τ→ν¯τe¯ν𝑒, τ¯→ν¯τπ+, and τ¯→ν¯τπ+π0; other decay modes may be included in a straightforward fashion. We show results for transverse momentum and rapidity variables in leading-log and next-to-leading-log approximations; the leptonic observables are compared to similar observables from direct W→e¯ν𝑒.
