Calculating the two-pion decay and mixing of neutral K mesons
Norman H. Christ (for the RBC and UKQCD Collaborations)🇺🇸
Abstract
The recent calculation of the complex isospin-two decay amplitude A_2 with physical kinematics is presented together with exploratory calculations of the isospin-zero decay amplitude A_0. Prospects for accurate calculation of A_0 as well as the mass difference between the K_L and K_S mesons are discussed.
