Here, we present a measurement of the effective weak mixing angle parameter sin2θℓeff in $$p\bar{p}$$ → Z/γ* → μ+μ– events at a center-of-mass energy of 1.96 TeV, collected by the D0 detector at the Fermilab Tevatron Collider and corresponding to 8.6 fb–1 of integrated luminosity. The measured value of sin2θℓeff[μμ] = 0.23016 ± 0.00064 is further combined with the result from the D0 measurement in $$p\bar{p}$$ → Z/γ* → e+e– events, resulting in sin2θℓeff[comb] = 0.23095 ± 0.00040. This combined result is the most precise measurement from a single experiment at a hadron collider and is the most precise determination using the coupling of the Z/γ* to light quarks.
