摘要：I report on the application of tmQCD techniques to the computation of hadronic matrix elements of four-fermion operators. Emphasis is put on the computation of BK in quenchedQCD performed by the ALPHA Collaboration. The extension of tmQCD strategies to the study of neutral Bmeson mixing is briefly discussed. Finally, some remarks are made concerning proposals to apply tmQCD to the computation of K →pp amplitudes.
