Description

Single top quark is mainly produced through the t-channel W boson exchange q + b -> q + t at LHC. This process probes Wtb vertex directly and can be used to measure the CKM matrix element Vtb or constrain the bottom quark PDF. The non-factorisable contributions are the last missing piece of the NNLO QCD correction. In this talk, I will first motivate the computation of these corrections, then I will discuss the calculation procedure and techniques we applied in this work. Finally I will present some results.
