Abstract

One of the main challenges of the Tevatron at Fermilab and the Large Hadron Collider (LHC) at CERN is the determination of Standard Model (SM) parameters at the TeV scale. In this context various processes will be investigated which involve bottom-quark jets in the final state, for example decays of top-quarks or gauge bosons of the weak interaction. Hence the theoretical understanding of processes with bottom-quark jets is necessary. In this paper analytic results will be presented for the weak corrections to bottom-quark jet production -- neglecting purely photonic corrections. The results will be used to study differential distributions, where sizeable effects are observed.
