Near-Threshold Production of , , and at a Fixed-Target Experiment at the Future Ultrahigh-Energy Proton Colliders

Figure 2

Cross sections for Standard Model boson production in proton-proton collisions at various centre-of-mass (lower -axis) and corresponding beam energies in the fixed-target mode (upper -axis). The color bands indicate the 1- values coming from the PDF uncertainty. The NLO calculations were performed with CT10NLO [27] by using MCFM [28] with set to the mass of the produced particle. The 4 orange arrows point at the beam energy of the 4 setups which we have considered.
