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 𝑚&sup(2)&sub(𝜋) and 𝑚*2&sub(𝐾) to second order in 1/𝑁&sub(𝑐) expansion. The result is an algebraic cubic curve whose coefficients are the known Weinberg values for the quark mass ratios 𝑚&sub(𝑢)/𝑚&sub(𝑑) and 𝑚&sub(𝑠)/𝑚&sub(𝑑). Additional restrictions arise when using the ratio 𝑚&sub(𝑠)/𝑚&sub(𝑢𝑑)=27.23(10) quoted by FLAG for lattice simulations with four quark flavors. This provides a tight constraint on the ratio 𝑚&sub(𝑢)/𝑚&sub(𝑑)=0.455(8).
