As a simplified example, if a beamline runs for 8 hours (28 800 seconds) at an instantaneous luminosity of 300 × 10 cm ⋅s = 300 μb ⋅s, then it will gather data totaling an integrated luminosity of 8 640 000 μb = 8.64 pb = 0.008 64 fb during this period. If this is multiplied by the cross-section, then a dimensionless number is obtained equal to the number of expected scattering events.
