Updated Estimate of Running Quark Masses

Abstract

Stimulated by recent development of the calculation methods of the running quark masses $m_q(μ)$ and renewal of the input data, for the purpose of making a standard table of $m_q(μ)$ for convenience of particle physicists, the values of $m_q(μ)$ at various energy scales $μ$ ($μ= 1$ GeV, $μ= m_c$, $μ=m_b$, $μ=m_t$ and so on), especially at $μ= m_Z$, are systematically evaluated by using the mass renormalization equations and by taking into consideration a matching condition at the quark threshold.
