Ratios of the Light Quark Masses: Cubic Curve Versus Ellipse / A.A.Osipov // Physical Review D [Electronic resource]. – 2024. – Vol. 110, No. 1. – P. 014044. – URL: https://doi.org/10.1103/PhysRevD.110.014044. – Bibliogr.: 44.
The bounds on the light quark masses are obtained by fitting the squares of pseudoscalar meson masses 𝑚2 𝜋 and 𝑚2 𝐾 to second order in 1/𝑁𝑐 expansion. The result is an algebraic cubic curve whose coefficients are the known Weinberg values for the quark mass ratios 𝑚𝑢/𝑚𝑑 and 𝑚𝑠/𝑚𝑑. Additional restrictions arise when using the ratio 𝑚𝑠/𝑚𝑢𝑑=27.23(10) quoted by FLAG for lattice simulations with four quark flavors. This provides a tight constraint on the ratio 𝑚𝑢/𝑚𝑑=0.455(8).
