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

Table 2

Luminosities reachable in the fixed target mode. The proton flux is calculated by assuming that 5% of the beam is used per fill of 10 hours. The luminosities are calculated for the case of targets that are 1 cm thick. The three values displayed represent luminosities for three different targets: liquid hydrogen, beryllium, and tungsten. The gas-target values are calculated using the same parameters as in [19] for a perfect gas at a pressure of Bar in a zone of 100 cm.
