Impact of the heavy-quark matching scales in PDF fits

Abstract We investigate the impact of displaced heavy-quark matching scales in a global fit. The heavy-quark matching scale $$\mu _{m}$$ μ m determines at which energy scale $$\mu $$ μ the QCD theory transitions from $$N_{F}$$ N F to $$N_{F}+1$$ N F + 1 in the variable flavor number scheme (VFNS) fo...
