Lattice calculation of the mass difference between the long- and short-lived K mesons for physical quark masses
The two neutral kaon states in nature, the 𝘒_𝐿 (long-lived) and 𝘒_s (short-lived) mesons, are the two time-evolution eigenstates of the 𝘒⁰ - 𝘒̅⁰̅ mixing system. The prediction of their mass difference 𝚫m_𝘒 based on the standard model is an important goal of lattice QCD. Non-perturbative formalism ha...
