Electroweak input parameters, in the scheme, for the NC and CC Drell–Yan pp and deep inelastic ep scattering cross-section calculations, see text. Standard Model parameters are taken from Refs. [39, 100], except . The symbols denote the elements of the CKM matrix. The parameters below the line, the weak mixing angle , the fine-structure constant , and the vector couplings of up-type quarks , down-type quarks , and charged leptons to the Z boson, are calculated at tree level from the ones above
