An investigation of the ${\alpha }_S$ and heavy quark mass dependence in the MSHT20 global PDF analysis

T. Cridge, L. A. Harland-Lang, A. D. Martin +1

We investigate the MSHT20 global PDF sets, demonstrating the effects of varying the strong coupling ${\alpha }_S(M_Z^2)$ and the masses of the charm and bottom quarks. We determine the pre…
