Consider the p̅p Tevatron collider working at √s ≈ 2 TeV. For a Z produced at rest, what are the approximate momentum fractions of the annihilating quark and antiquark? Evaluate in which fraction they are sea quarks. If the Z is produced with a longitudinal momentum of 100 GeV what are the approximate momentum fractions of the quark and of the antiquark?
