Phenomenology using lattice QCD

Abstract

This talk provides a brief summary of the status of lattice QCD calculations of the light quark masses and the kaon bag parameter B_K. Precise estimates of these four fundamental parameters of the standard model, i.e., m_u, m_d, m_s and the CP violating parameter eta, help constrain grand unified models and could provide a window to new physics.
