Description

This talk will review the importance of the calculation of B_K, the strong interaction correction factor needed to quantify CP violation in the mixing of neutral K mesons. The review will be followed by a summary of estimates of B_K using lattice QCD. Finally, I will give a critical analysis of current estimates of statistical and systematic errors and what improvements will be made in future calculations of matrix elements of 4-fermion operators.
