Abstract

We study the effects of dimension six effective operators on the production of single top quarks at the CERN LHC. The operator set considered includes terms with effective gluon interactions and four-fermion terms. Analytic expressions for the several partonic cross sections of single top production will be presented, as well as the results of their integration on the parton density functions.
